How do you factor a quadratic expression?
Back
To factor a quadratic expression of the form ax² + bx + c, find two numbers that multiply to ac and add to b, then rewrite the expression as (px + q)(rx + s).

FLASHCARD QUESTION
Front
What is the vertex form of a quadratic equation?
Back
The vertex form is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
