What is the GCF (Greatest Common Factor)?

Back

The GCF is the largest factor that two or more numbers have in common. It is used to simplify expressions before factoring.

How do you factor a quadratic expression of the form ax^2 + bx + c?

Back

To factor a quadratic expression, look for two numbers that multiply to ac (the product of a and c) and add to b. Then, rewrite the expression using these numbers.
