I can solve quadratic equations by factoring.

Part 1 of 3

Key concepts

3 concepts

  1. 1

    A quadratic equation has a degree of two, and solving it means finding the values that make the equation true.

  2. 2

    Factoring a quadratic expression involves breaking it down into a product of two linear expressions, such as (px + q)(rx + s) = 0.

  3. 3

    The zero-product property states that if the product of two factors equals zero, then at least one of the factors must be zero.
