How to solve 3 degree polynomial
Did you know?
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. WebJun 8, 2024 · To solve a third degree equation, it would be helpful if we know one solution (or root) to start with. By knowing one solution (remember every cubic equation has at least one solution) we proceed by factoring the third degree equation into a product of a first degree polynomial (using the solution we know) with a second degree polynomial.
