|This quiz focuses on factoring polynomials when terms have a common factor. To factor, we express a polynomial as a product using the distributive law in reverse:
ab + ac = a (b + c) and ab - ac = a (b - c).
In each case, the GCF of the terms is "a."
Factor 7x^2 + 14.
The GCF of both terms is 7 so 7x^2 + 14 can be written as
(7 * x^2) + (7 * 2)
7 (x^2 + 2)
