The Wrong Answer At the video time 7:34, while doing this problem, she got it wrong. The problem was (4x^3+13x^2-5x+1). Her answer was 101. The problem’s actual answer was -27. The last bracket problem was: (-256+208+20+1). Instead of putting in -256, she took half of it, and wrote -128.
Thanks To Entire Group carrier Ride .Your Way of teaching is very short but fullfill the demand of competition,It save time. Thank You . In Question No 11 if we substitute 10 10 and 5 in a b and c resp we will got ans 40000 .and your answer is 160000 .which one is right.please elaborate.
In Practice Question 1. The answer is -1 is we solve question taking (x,y) values (0,1) but it is giving wrong answer 3 on taking values (1,0) which we can also take as given equation being satisfied x + y = 1 Please Answer???
Mam... A small doubt... In q4 if x^2 = 4 means.. how can we simplify it with 3x^3 ? Can it be calculated?... It must be 27x ie. 3x3x3.. 27. pls Clarify it
So then should we go for traditional approach instead of substitution? But that will also be lengthy, this method not providing correct result all the time.@@mathmyth9061
Question number 10 -> "your approch is totally wrong" its not workiong, if we assume another value of y and then get the value of x according to given equation and then put the values in expression will get different answer. please take care of this . cant expect such a mistake from you.
For any equation, if you change one variable, the other will also change accordingly to keep the balance but the balance would stay for the equation to exist. .
I guess they are considering root2 cube as root2 x square of root2 then sq of root2 = 2 and then multiply it with 27 we will get 54 and write that root2 as it is... I don't know what logic I've applied but that's how only it can come 54 root2 I guess...
How come 4(_4)^3 become 128. You also make me confused regarding the changes in symbol(_,+).In some case,_.(_) turn '+' but in other it's the opposite.
59:15 calculation mistake...its( -)formula....so it would be -2 ...25+2=27 ans
In question no.1 7:54 you did calculation mistake in the first part of calculation 4(-4)3 will be -256 not -128.
& then answer will be -27 , right ?
@@kang200-2 yes..
Yes reminder is -27
But remainder minus me
@@harshitasingh7243 remainder must not be in negative
16:36 Real Motivation
We can't forget about the contribution of "x" in algebra....
madam in the 1st q 4(-4)cube will be -256 but you write it -128
i also notice this

Yes exactly
Yeah
Love your way of explanation,
Thanks to the entire careerride team especially u mam🥰🥰
Synthetic division is also a useful approach to solve the questions explained in the start using remainder theorem .

Thank You .
In Question No 11 if we substitute 10 10 and 5 in a b and c resp we will got ans 40000 .and your answer is 160000 .which one is right.please elaborate.
maam in eg 15a i think it would be x^2+1/x^2 -2 insted of +2 so the ans would be 25+2 =27
please confirm
You are right, beta. That's a mistake. It should be 27.
what will happen if we substitite x=0, then y=-3/5. and when substituting y=-3/5 in the eqn then the answer is different. in Q10
yes also if x=2 then the ans is 6
finally i can understand algebra thankyou mam!
Alot thanks from me,such type of information....🙏🏻🙏🏻
Nice lecture mam.
Mam can you please complete CAT exam quant section ?
In Practice Question 1. The answer is -1 is we solve question taking (x,y) values (0,1) but it is giving wrong answer 3 on taking values (1,0) which we can also take as given equation being satisfied x + y = 1
Please Answer???
their might be question misprint it should be -2y^4
Mam In qn 15a. 59:11 the formula is wrong. The answer is 27 instead you've calculated as 23
Mam... A small doubt... In q4 if x^2 = 4 means.. how can we simplify it with 3x^3 ? Can it be calculated?... It must be 27x ie. 3x3x3.. 27. pls Clarify it
best lec till now maam loved it❤❤❤❤❤❤❤
35:01 in 10th sum y don't we assume x=2 and y=-1 then the equation becomes correct
It is amazing
Mam plz explain q6
Hello Ma'am, is quadratic equation covered?
No, Rahul.
question: 11 38:08 if we take a=10, b=10 and c=5 then answer will be 40000. Verify
1:17:56 if we take x=1 & y=0 then answer = -1 that's true.. but instead if we take x=0 & y=1 then result = 3 which is not same as answer. Verify
@@mathmyth9061 yeah i did the same

Thanks
Mereko vi dedo 😭
55:20 ma'am you forgot to square the other side of the equation (The answer of the question will be 9 I have used a different method)
If you don't no basic this channel not for you
There is a mistake in question number 1, in place of -128 it will be -256.
in question no 10 34:36 if we put x=2,y=-1 then ans =6 what to do in such case?
yes same doubt
Question number 10 -> "your approch is totally wrong" its not workiong, if we assume another value of y and then get the value of x according to given equation and then put the values in expression will get different answer. please take care of this . cant expect such a mistake from you.
Nyc lec mam , really loved it❤️❤️
Good lecture mam. Very useful
thank you
At 59:40 you apply formula of (a+b)² wrong use formula of (a-b)² so ans of that qu, is 27.
You saved my life😊
A wonderful video madam..thanks a lot
Firstly, I would like to thanks you guys.
Secondly, mam in Q.12 try subsituting a=2. Then answer is coming 0. Explain?
much needed video , thanks a lot >>>>>>
Very Interesting🤔 thanks 🙏🙏🙏🙏
Q9- If we take X=2 and Y=-1 then answer changes
Thankyou Ma'am
15 question 25+2 na as it was( x-1/x)^2
Is the question at 32:49 wrong? Because taking x = 0 and y = 0 gives different answers
mam in qn 10 i put x=0 and getting different answer what is wrong? i am getting y to be -3/5
this mam caught me.... when the video started i was thinking about my ex and all that stuff
😂
India ka vikas hoga jrur hoga asi hi video se Indian bhaiyo ko profit.
in qn 15 it should be opposite right?

Thank you 😊
in Q11 how sign will be changed + to - ? in (a^3 - 3a) instead of that (a^3 +3a) ?
Its actually Q16 how it became (-)
Reasoning me add on kijiye like cube,cut and fold type questions
Good 👍
Mam u are asuming y =0 what if i assume 1 , the answer would change .
For any equation, if you change one variable, the other will also change accordingly to keep the balance but the balance would stay for the equation to exist. .

With q.16 1:05:00 , how did you get 54 root 2, isn't it supposed to be 27 root 2, don't we have to cube the square root as well?
I guess they are considering root2 cube as root2 x square of root2 then sq of root2 = 2 and then multiply it with 27 we will get 54 and write that root2 as it is... I don't know what logic I've applied but that's how only it can come 54 root2 I guess...
27 is correct
There are 3 √2 so 3√2*3√2*3√2=3*3*3*2*√2

Ma'am Please Make a Video On Harmonic Progression
ok. Suggestion taken :)
in q9 if we take x=0 y=1 then answer changes
In question no. 15a we have to add 2 in last step but you subtracted...
You are right. That's a mistake. Please correct it while taking down your notes.
I have gone through carrerride test practice set for different chapters and I must say they 50% ans, solution are wrong
Can anyone tell me about q9 16:40 how we can take 5^x-1 common?
5^x - 5^(x-1)
= 5^1 x 5^ (x-1) - 5^(x-1)
Now you can take common out
add and sub the 1 in the first 5
Thank you mam.
Can someone explain me,how are we to take 5 to the power x-1 common and get 5 as a remainder from the left hand side of the equation?
i didn't understand that either
you can take 5powX common -> 5powX - 5powX-1 = 5powX+1 - 5powX = 5powX * (5-1)
ma'am took 5powX-1 as common, both way is correct.
15.a.answer should be 27
Thankyou so much, But please do not use english since it's a logical vedio so you would have to keep an eye on how your english is coming in vedio

First math question answer was wrong.
Mm..ss...
Answer is = -27
Not -128 ....-256. ✓
Is ans for 13a 23 or 27?
You mean 15(a) ? The answer should be 27.
Thank you madam
15 a is 27 not 23
1 and 2 questions are not clarity values are wrong
