Solving Quadratics By Factoring

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

What does it mean to factor a quadratic equation?

Back

Factoring a quadratic equation means rewriting it as a product of two binomials, such as (x + p)(x + q) = 0, where p and q are the roots of the equation.

How do you find the roots of a quadratic equation by factoring?

Back

To find the roots, factor the quadratic into the form (x + p)(x + q) = 0, then set each factor equal to zero: x + p = 0 and x + q = 0.
