WebSo the hardest part of factoring a cubic polynomial in general is finding a real root. Once a root r r is found, the polynomial factors as f (x) = (x-r)g (x), f (x) = (x−r)g(x), where g (x) g(x) is quadratic, and quadratic polynomials can be factored easily via the quadratic formula. Techniques for finding a real root of a cubic polynomial ... WebStandard form of the Cubic Polynomial p (x) = ax 3 + bx 2 + cx + da ≠ 0 A. The “ad” Method for Linear Factors This method is named ” ad “ because coefficients a and d play a central role in the factorization process. In this method, we split the coefficients b and c of the standard cubic polynomial as:
