Solving Quadratic equations 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 expression?

Back

Factoring a quadratic expression means rewriting it as a product of two binomials, such as (px + q)(rx + s), where the product equals the original expression.

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax² + bx + c = 0.

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

Back

To find the roots, factor the quadratic into the form (x - r1)(x - r2) = 0, then set each factor equal to zero and solve for x.
