Question

how many factors of a cubic expression have?​

Answer 1

Answer:

Let the values which are factors of a constant term and check the polynomial for that values. You will get three factors.

Answer 2

In general, to factorise a cubic polynomial, you find one factor by trial and error. Use the factor theorem to confirm that the guess is a root. Then divide the cubic polynomial by the factor to obtain a quadratic. Once you have the quadratic, you can apply the standard methods to factorise the quadratic
