Essential Stuff Essential Question Essential Vocabulary How do you solve quadratic equations by factoring? Essential Vocabulary Quadratic Equation Factoring Roots Zero

Quadratic Equations The general form of a quadratic equation is 𝒚=𝒂 𝒙 𝟐 +𝒃𝒙+𝒄

Quadratic Equations To solve quadratic equations Factor and set equal to zero Using Square Roots Quadratic Formula Calculator

Solve by Factoring Zero Product Property If ab = 0, then a = 0 or b = 0 or a = b = 0 So, to solve we need to set the equation equal to zero and find the x-intercepts.

Solve by Factoring Solution to a quadratic equation: Root of the Function Zero of the Function The solution to a quadratic equation is the value where the graph crosses the x-axis.
