I feel proud of those who praised this lecture but to me I could not understand how you came up with these magic fractions to obtain factors.

Do you have a similar video for finding the factors if the coefficient of x^3 is 1 and the other two roots are found through the quadratic formula?

[augustadjurnic]

Thank you for the video it was really helpful ive been struggling with this !

[esrakuser]

Can we solve the first example by (one of the factors is 1 since the sum of coefficients are 0), then synthetic division by (w-1)

[VickySingh-ldkq]

Thanks for this video . It is very useful for me

Sir if x cube coefficient is greater than x square coefficient

[HamidSain]

Hi Professor,
why +/-7 isn’t one of the possible divisor?

[mukeshkhinchi]

If a cubic equation contain a=1, b=12.3, c=3.74, d=1.68.
Then it's difficult to find all roots, then how would we get the roots.And I want use hit and trial method then...

[shivarajgowda]

I'm new student I want to know how to find possible divisors while I am solving qubic equations

[sanjeevkumarshah]

if the last number is -1 and the coeficient of x square is -3/2 then what will be the factor. please tell me

[beesknees]

Holy shit you are so goood damn my teacher taught me some long ass method that i didnt understand but this wow i subbed and liked

This is a great method it's very useful but his voice is great! Lol

[harpergrace]

How would you apply this in x^3-8x-3=0, x^2=0?
