WebJan 29, 2024 · A simple way to factorize depressed cubic polynomials of the form. (1) x 3 + A x + B = 0. Is to first move all the constants to the RHS, so ( 1) becomes. (2) x 3 + A x = − B. Now, find two factors of B such that one fact minus the square of the other factor is A. We'll call them a, b so. (3) a − b 2 = A (4) a b = − B. WebStep 1: Find a root, say 'a', of the cubic polynomial. Then (x - a) is the factor. (This can be one of the prime factors of the constant term of the polynomial) Step 2: Now, divide the linear factor by the cubic polynomial to find a quadratic factor of the polynomial.
