Factoring Polynomials

Factoring PolynomialsOnce 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
