How to factor any cubic function
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) … Web24 de abr. de 2024 · Brought to you by Sciencing. Solve each factor: 2x + 1 = 0 becomes 2x = -1 which becomes x = -1/2 x – 1 = 0 becomes x = 1 X + 1 = 0 becomes x = -1 Solutions: x = ±1, -1/2 These values of x when plugged into the original equation make the equation true; that is why they are called solutions. Let the equation be in the form ax³ + bx² + cx ...
