Once we factor a polynomial, we are trying to find simpler
polynomials that could be multiplied together to provide us the polynomial that
we began with. You may want to review multiplying polynomials in case you are
not totally clear on how that functions.

Whenever we factor a polynomial, we are often only thinking
about breaking it down into polynomials which have integer coefficients and
constants.

**Factoring
Polynomials by Grouping**

**To factor a
polynomial you should decrease the polynomial expression to its factors.**

We are going to utilize a method called the 'ac' approach to
factor by grouping. Lots of people do not understand that there is a systematic
method to factor by grouping. This is the closes thing to some formula that you
will find for **factoring polynomials by
grouping**.

**Formula for Factoring
By Grouping**

If you possess a quadratic equation in the type ax2+bx+c

**Step 1)** Figure
out the item of AC (the coefficients in a quadratic equation)

**Step 2)** Figure
out what factors of a·c sum to b.

**Step 3)** ungroup
the middle phrase to become the amount of the factors present in step 2

**Steps 4) **group
the sets.

**Factoring
Cubic Polynomials**

A cubic polynomial is actually a polynomial of the form
