How do you factor a quadratic expression in the form x² + bx + c?

Back

To factor x² + bx + c, find two numbers that multiply to c and add to b, then rewrite the expression as (x + m)(x + n), where m and n are those numbers.

Front

How do you factor x² - 2x - 24?

Back

To factor x² - 2x - 24, find two numbers that multiply to -24 and add to -2. The factored form is (x + 4)(x - 6).

Front

What is the process for factoring a quadratic expression of the form ax² + bx + c?

Back

The process involves finding the greatest common factor (if any), identifying two numbers that multiply to ac and add to b, and then rewriting the expression in factored form.
