1 Solving Quadratic Equations by Graphing!

2 Quadratic functions vs. Quadratic equations Quadratic fxns are written in the following form f(x) = ax² + bx + c Quadratic Equations are when a quadratic fxn is set equal to a number ax² + bx + c = 0

3 Solutions of a quadratic equation ROOTS are solutions to a quadratic equation. ** To find the roots of a quadratic equation, we find the zeros of the related quadratic function. ZEROS are the x-intercepts of the graph. f(x) = 0 at these points

4 Quadratic Equations can have 1.Two real solutions 2.One real solution 3.No real solutions

5 EXAMPLES!!

6 If absent, please see Examples 1-4 in section 6-2. Assignment pg 297 #1,3,16-18,24,26,32,42,67,70,71
