For those who didn't understand he did 2 x 15 = 30 and the factors of 30 must = to -11 so -6 x -5 = 30 as well as -6-5=-11 (that is the step he didn't show)
It’s easier to do slide and divide! We have the equation in ax^2 + bx + c format Therefore, 2x^2 - 11x + 15 Take the coefficient (the two in front of the X) and slide it over and multiply it with 15. 2 • 15 = 30 Now we have x^2 - 11x + 30 (but keep the coefficient for later! Or write it down so you don’t forget!) Now find what adds to get ‘b’ (-11) and what multiplies together to get ‘c’ (30) If you find the factors, it’s -5 and -6 So you can plug those in with x^2 (x - 5) (x - 6) but it’s not done! Remember the coefficient (2) we saved for later, now we’re going to divide our numbers by that! (x - 5/2) (x - 6/2) Our 6/2 can divide into 3! So we have (x - 3) for one of our parts. The 5 does not divide, so we just bring that ‘2’ in front of the x instead! (2x - 5) And now we put them beside each other (2x - 5)(x - 3) It sounds harder than it actually is, but it’s super easy to remember the steps especially for tests and stuff Source: I’m a college tutor 💀
U multiple the coefficient of the first number with the last number of the sum and then u take the last number and the middle number and find two numbers that are the same when added and multiplied
2x divided by 2x^2 = x 2x divided by -6x = - 3 He is dividing the number outside the parenthesis. E.g 2x( )and -5( ) he got 2x from 2x^2 and -6x cause their GCF is 2x. And same with -5 is the GCF of -5x and 15.
First you have to multiply the 2 from 2x^2 to the 15 which gets you 30, now you have 30 and -11, -6 and -5 both get you 30 and -11 In other words multiply the a and c value then see what numbers fit into the product of those two numbers and the b value Ax^2 +Bx = C Hope this helps 🙏
Bro so simple just multipley the last term with the first term so 15 x 2 = 30 , then when you a add 6 + 5 it's equal to 11 and 6× 5 is equal to 30 there should be this relation then only it means we splited the middle term correctly .
You need to multiply the coefficient of x² by the number without an x and then find 2 numbers which multiply to make the same thing, and add to make the number in front of the x. 2×15=30 and -6×-5=30 and -6-5=-11 so you split it to make 2x²-6x-5x+15

We have the equation in ax^2 + bx + c format
Therefore, 2x^2 - 11x + 15
Take the coefficient (the two in front of the X) and slide it over and multiply it with 15.

Now find what adds to get ‘b’ (-11) and what multiplies together to get ‘c’ (30)
If you find the factors, it’s -5 and -6
So you can plug those in with x^2
(x - 5) (x - 6) but it’s not done!
Remember the coefficient (2) we saved for later, now we’re going to divide our numbers by that! (x - 5/2) (x - 6/2)
Our 6/2 can divide into 3! So we have (x - 3) for one of our parts. The 5 does not divide, so we just bring that ‘2’ in front of the x instead! (2x - 5)
And now we put them beside each other
(2x - 5)(x - 3)

If the 5 was 8, will x still have 2 at the end: (2x-8)(x-3) or (x-4)(x-3)?
Nope 8 multiple doesn't give 30 as product@@veljkodjuric6877

I'm taking pre-cal again... and videos like this help. I need to pass this class 😢
How peculiar to play loud music as the soundtrack to a maths video, of all things!
It's (2x - 5)(x-3)
That's the easiest method.
Ain't no way nobody is talking abt the handwriting 💀 it's to good
I love this method it makes sense❤
Koi sense nhi hai 😅😅😅
You missed the 6x+5x:11 you known that see your answer 😅😅😅😅😅
why did you know six plus five to eleven how did you realize it i wanna know the process
U multiple the coefficient of the first number with the last number of the sum and then u take the last number and the middle number and find two numbers that are the same when added and multiplied
Easier if you use slide and divide..But you are still correct..Congratz
Please how did he get ( x-3)-5(x-3)
2x divided by 2x^2 = x
2x divided by -6x = - 3
He is dividing the number outside the parenthesis. E.g 2x( )and -5( ) he got 2x from 2x^2 and -6x cause their GCF is 2x. And same with -5 is the GCF of -5x and 15.

Sir where you get 6x and 5x
How did they get the 3?
Music was annoying 😡😡
The music was distracting me
Reduce ur volume from ur phone
remeber x²+x=x(x+1)
Does it matter wich order you write the answer in...like is it okay if I wrote
(×-3)(2×-5)?
Nope, multiplication is commutative, so that means it doesn't matter which order you write the brackets
Amazing 😊
Where did they get the 6
Non Monic Equations
Helpful
Thanks, this video helped
Where should you get 6 and 5 😮
Hmm
By sliptting
Should the greatest common factor between -5x and 15 be +5? That's where I get confused.
negative times negative equals positive , therefore to get +15 you need -5
Where did you get 6 from??
-6-5= -11
Kuch ho sakta tera
Nhi
Bro easy

good job 👍👌
So amazing

Thanks you for help me
Abram morena if the sound or song it disturb u reduce your sound from ur phone 😁😁simple
Nice thank u
Dont think he found numbers that sum up to 11😂
Where you get that 6????
Same query
First you have to multiply the 2 from 2x^2
to the 15 which gets you 30, now you have 30 and -11, -6 and -5 both get you 30 and -11
In other words multiply the a and c value then see what numbers fit into the product of those two numbers and the b value
Ax^2 +Bx = C
Hope this helps 🙏
Can somebody explain the last step where she gets 2x-5 and x-3. I dont understand where the other x-3 term went
2x(x - 3) - 5(x - 3)
= 2xa - 5a [a = x - 3]
= a(2x - 5)
= (x - 3)(2x - 5) [Putting the value of a]
Where do you get 6 & 5
Multiply 15 with 2(coefficient of x^2) and you get 30. Now find two numbers that multiply to 30 and adds to -11 which is -5 &-6
Middle term bro this is easy for class 7

Im confused
(x-3) (2x-5) correct answer hai

5x2-24x-5=0
Anybody
3 , 5/2
Why is -6 and -5 couldn’t it be like -7 -4? I need help
15×2=30
30= 5×6
-11= -5-6
when you'll do grouping, -5 will be common with 15 and -6 for 2
Bro so simple just multipley the last term with the first term so 15 x 2 = 30 , then when you a add 6 + 5 it's equal to 11 and 6× 5 is equal to 30 there should be this relation then only it means we splited the middle term correctly .
When need to find factors of middle terms such that they multiple equal to coefficient of xsquare and the constant term

Draw a x bro
How did you get 6
You need to multiply the coefficient of x² by the number without an x and then find 2 numbers which multiply to make the same thing, and add to make the number in front of the x. 2×15=30 and -6×-5=30 and -6-5=-11 so you split it to make 2x²-6x-5x+15
bro doesn’t know slip and slide

Tip a nhi ha samja ha
Its so easy😂😂😂
2x²-11x+15=0
x²-11x+30=0
(x-5)(x-6)=0
(2x-5)(x-3)=0
2x-5=0
2x=5
x=5/2
x=2,5
x-3=0
x=3
You forgot the power 2.
Yes maths good shbash girl😂
Wait but what then happens to the square on top of the 2
When you multiply both parentheses, it should give you 2x^2 -11x + 15 because you're just factoring the equation

istg bro, this method is faster than my school's method, I hope my teacher accepts this method in the exam
Thank you so much

Bro I'm soo tired
It is wrong😅
Bro it was direct you need to show one ster
pls someone explain the last step
bro 2x(x-3)-5(x-3)
so (x-3) is common there
so it can be written as (x-3) ( 2x-5)

What mods you did to the car???
Stage 2 tune, downpipe, cold air intake, carbon fiber rims
Then what about 6x5=30 but you have to get 15 by multiplying them
30 is divided by 2 since there is a 2x as one of the factors
