Step-by-step explanation:

Factoring a polynomial is one important way to find the roots (or x-intercepts) of the polynomial.  It's not always the easiest method, particularly when the roots are mixed numbers.

If you take calculus later, you'll see that finding the derivative of a function, setting this derivative = to 0 and solving for the roots is one way in which we can identify the x-value(s) at which we have either a maximum or a minimum.
