Factoring Polynomials Using GCF

¥  Factoring: Write the polynomial as a product.

Steps:

1.  Find the GCF of all its terms.

2.  Write the polynomial as a product by factoring out the GCF from all the terms.

- This is done by dividing the original terms of the polynomial by the GCF.

3.  The remaining factors in each term will form a polynomial.
