With quadratic equations if you put in anything as A B and C you'll get a simple answer. In cubic equations only a fraction of equations are simple, most are very long
Simply put x=1 or -1 and check whether it is equal to 0 or not. That little complicated stuff you showed for checking x=1,-1 came from the same logic but the former idea doesn't need anything to be to be memorized. Thanks for a good explanation in other cases. Liked it.

2x^3+x^2-13x+6=0 On observation, x=2 satisfies this equation (x-2)=0 is a factor of 2x^3+x^2-13x+6=0 (2x^3+x^2-13x+6)/(x-2)=(2x^2+5x-3)=0 using synthetic division. In 2x^2+5x-3 b^2>4ac therefore 2x^3+x^2-13x+6 has three real roots. (x-2)(2x^2+5x-3)=0 x= -3 is a solution by observation (x+3)=0 is a factor of (2x^2+5x-3)=0 (2x^2+5x-3)/(x+3)=(2x-1)=0 using synthetic division. (2x-1)=0 is a factor of 2x^3+x^2-13x+6=0 Therefore,(2x^3+x^2-13x+6)=(x-2)(x+3)(2x-1)=0 Hence x=2,x= -3 and x=1/2 are the three real roots of 2x^3+x^2-13x+6=0 Thanks for the puzzle PreMath.
I think the method explained is rather a trial-and-error approach and the following method will be more logical: Let us consider the LHS of the equation as y and as x approaches to plus infinity, y also approaches to plus infinity; similarly, when x approaches to negative infinity, y also approaches to negative infinity. What does this mean? This means y is a continues function sloping in the NE-SW direction. Meantime, x = 0, y = 6 and x = 1, y = -7 which means that there will be a real root between 0 and 1. As y is sloping in the NE-SW direction, we can deduce that there has to be 3 real distinct roots to y. When x = -1, y = 18; This clearly indicates that the 3 real roots to function y namely α, β and γ (say α

In case of cubic equation point of view, At first one of the root should be obtained by applying "hit & trail method "(Although it needs some simplification in some cases ), Then other roots may come out by deviding the first root (suppose the first root is 7, then you have to devide the given equation by x-7), then move on (personal opinion )
The check by comparing the sum of the roots against -B/A is going to come in handy! Thx!! Quick Question: Does this answer check work when there are 1 real root and 2 complex roots?
This is just the way I did it (taking hints from highest power, constant term and Vieta) before seeing the video solution ... 2x³+x²-13x+6=0 Looking at the equation. Based on the 2x³ term, 2x-1 might be a solution (plug in x=1/2 - it is). Based on the constant term x+3 might be a factor (plug in x=-3 - it is). Vietas rule/formula says sum of solutions = -b/a -1/2 = 1/2 -3 + r (r is the third root) r=2 verfiy ... (2x-1)(x+3)(x-2)=2x³+x²-13x+6 In this case the guesswork was fine - the above two were the only guesses I tried. It is not always so. For example I might have guessed a more complicated (2x+3) as a factor.

There's a cubic equation formula or algorithm somewhere that can be used to solve all cubic equations. Also, though this example is instructive, it does not show how the methods work.

These things were taught to me in the ‘elementary differential equations’ course. I forgot them because I took that course a long a while. You refreshed it to me and you taught me something new which our teacher in the past didn’t, which is the checking methods whether the answer is x=+-1 or our set of solutions of the equation is true. This would’ve changed my grade into better if I had the chance to see it when I was taking the course. But anyways, Thanks a lot. Edit: It turned out actually you uploaded this video after I finished the course after I checked the time it was uploaded.

On observation, x=2 satisfies this equation

(2x^3+x^2-13x+6)/(x-2)=(2x^2+5x-3)=0 using synthetic division.
In 2x^2+5x-3 b^2>4ac therefore 2x^3+x^2-13x+6 has three real roots.
(x-2)(2x^2+5x-3)=0
x= -3 is a solution by observation
(x+3)=0 is a factor of (2x^2+5x-3)=0
(2x^2+5x-3)/(x+3)=(2x-1)=0 using synthetic division.
(2x-1)=0 is a factor of 2x^3+x^2-13x+6=0

Looking at the equation.
Based on the 2x³ term, 2x-1 might be a solution (plug in x=1/2 - it is).
Based on the constant term x+3 might be a factor (plug in x=-3 - it is).
Vietas rule/formula says sum of solutions = -b/a
-1/2 = 1/2 -3 + r (r is the third root)
r=2
verfiy ... (2x-1)(x+3)(x-2)=2x³+x²-13x+6
In this case the guesswork was fine - the above two were the only guesses I tried.
It is not always so. For example I might have guessed a more complicated (2x+3) as a factor.
For sure time is delayed in in certain intervals, but given consistent and smooth paths, time moves in polynomial steps
Thank you,in Hong Kong,they did not teach us those interesting properties,and just teach us to aim higher marks

Solve equation 2x^3+x^2-13x+6=0
Solve:
2x^3+x^2-13x+6
=2x^3-12x^2+24x-16+13x^2-37x+22
=2(x-2)^3+(13x-11)(x-2)
=(x-2)[2(x-2)^2+(13x-11)]
=(x-2)[2x^2-8x+8+13x-11]
=(x-2)[2x^2+5x-3]
=(x-2)[(x+3)(2x-1)]
=(x-2)(x+3)(2x-1)=0
So
x-2=0
x+3=0
2x-1=0
So
x1=2
x2=-3
x3=1/2
Verify:x1=2 or x2=-3 or x3=1/2 are all the root of the original equation
解方程2x ^ 3 + x ^ 2-13x + 6 = 0
解答：
2x ^ 3 + x ^ 2-13x + 6
= 2x ^ 3-12x ^ 2 + 24x-16 + 13x ^ 2-37x + 22
= 2（x-2）^ 3 +（13x-11）（x-2）
=（x-2）[2（x-2）^ 2 +（13x-11）]
=（x-2）[2x ^ 2-8x + 8 + 13x-11]
=（x-2）[2x ^ 2 + 5x-3]
=（x-2）[（x + 3）（2x-1）]
=（x-2）（x + 3）（2x-1）= 0
所以
x-2 = 0
x + 3 = 0
2x-1 = 0
所以
x1 = 2
x2 = -3
x3 = 1/2
验证：x1 = 2或x2 = -3或x3 = 1/2都是原始方程式的根

Thanks, I've been trying to solve the cubic for so long, and this video helped me a lot. Thanks again.
Nice....but it's a time taking procedure
At 1:30, to solve a cubic equation, why is it that if the sum of all coefficients sum to 0, 1 is always a solution?
if u plug in x for 1 into the equation, it equals 0
@@Duckeiigot it! Thank you so much!
He was even slower then sloth 🤣🤣😂😂🤣🤣
this is so helpful, thank you sir! gonna pass my test now
omg thank you for this example only one i could find with everything i needed to studuy
Ur Explaination is just awesome
Thanks it was helpful
Thanks Bir Amrit Singh for the feedback. Please share my channel with friends as well. Kind regards :)
There's a cubic equation formula or algorithm somewhere that can be used to solve all cubic equations. Also, though this example is instructive, it does not show how the methods work.
Glad I wasn't stuck with someone like him,....
Does this work for all cubic equations
Thanks sir
Dear Parveen Kachura , you are very welcome. Thank you so much for taking the time to leave this comment. I'm glad you liked the vid. Your feedback is always appreciated. Keep it up. Kind regards :)
Are you allowed to just type it into the calculator in the ccea as1 paper
These things were taught to me in the ‘elementary differential equations’ course. I forgot them because I took that course a long a while. You refreshed it to me and you taught me something new which our teacher in the past didn’t, which is the checking methods whether the answer is x=+-1 or our set of solutions of the equation is true. This would’ve changed my grade into better if I had the chance to see it when I was taking the course. But anyways, Thanks a lot.
Edit: It turned out actually you uploaded this video after I finished the course after I checked the time it was uploaded.
Sir thank you very much to give a deeper idea
Most welcome, dear
08:00 I didn't get the next factorization process
Nevermind i got it
I'm glad you got it!
Muhammed, I'm sure you are an awesome student 👍 I'm glad you liked it! Please keep sharing premath channel with your family and friends. Take care dear and all the best😃

Thank you sir you too
why does it feel like it is too complicated, just put the valus of 1,-1,2, and -2 instead of rembering all of this
Can you please explain me how does -1/2 came in LHS ?
