Factoring a cubic expression is the method of writing it as a product of three linear components. This may be accomplished by first discovering the roots of the cubic, that are the values of x that make the expression equal to zero. As soon as you already know the roots, you should use them to write down the components.
For instance, the cubic expression x^3 – 2x^2 – 5x + 6 may be factored as (x – 1)(x – 2)(x + 3). This may be accomplished utilizing the next steps:
