Equations involving three terms constant, linear, and square Take square root, factor or use quadratic formula Quadratic Equations

Factoring Since AB = 0 implies either A=0 or B = 0, then rewrite the quadratic equation as a product of linear factors.

Example 1

Quadratic Formula If factoring not nice, remember quadratic formula: For given quadratic equation, find solutions for x with: x =

Examples: x =
