WebFor polynomial of degree 3 you can use the following procedure. Assume that you guessed the solution x 1 = 4 (indeed 4 3 − 6 ⋅ 4 2 − 2 ⋅ 4 + 40 = 64 − 96 − 8 + 40 = 0). You can use Horner's method to get the polynomial p ( x) = p 2 x 2 + p 1 x + p 0 such that ( x − 4) ⋅ p ( x) = x 3 − 6 x 2 − 2 x + 40. WebAbout this unit.

Find the other zero, which give the two other x intercpets, by solving the equation x 2 + 3x + 1 = 0. The solutions are: x = -3/2 + SQRT(5) / 2 and x = -3/2 - SQRT(5) / 2.
WebOne way to see what's going on here is to rewrite the equation with all the i 's on one side: z 3 + 2 z 2 + 5 z = i ( z 2 + 2 z + 5) Factoring the left hand side as z ( z 2 + 2 z + 5), it's clear you can move things back to get ( z − i) ( z 2 + 2 z + 5) = 0 WebAug 28, 2016 · 1) Transform the equation to the form x 3 + 3 b x + c. I see you already did it. In your case you have the form y 3 + q y + r which is exactly the same. 2) Smartass trick: let y = w − b w. This transforms the equation into w 3 + c − b 3 w 3 = 0 which is a quadratic in w 3. So solve this 3) You now have a value for w. Can you find then a root now?
