Factoring a cubic expression is the process of writing it as a product of three linear factors. This can be done by first finding the roots of the cubic, which are the values of x that make the expression equal to zero. Once you know the roots, you can use them to write the factors.
For example, the cubic expression x^3 – 2x^2 – 5x + 6 can be factored as (x – 1)(x – 2)(x + 3). This can be done using the following steps:
