Warm-up 1.What are the different ways to solve quadratic equation? Solve the following problem by completing the square.

Objective - To solve quadratic equations by completing the square. Methods for Solving Quadratic Equations 1) Square Root Method (Doesn’t work with linear terms) 2) Graphic Method (Often difficult to tell) x=-1x=3 3) Quadratic Formula a=1 b= -2 c= -3 (Always works) 4) Factoring Method (Works when factorable) 5) Completing the Square (Always works)
