Section 5.8

1)by graphing (using the calculator to identify the roots (x-intercepts)) 2)by factoring 3)by “completing the square” 4)by Quadratic Formula: - can be used to solve ANY quadratic equation! Ways to solve quadratic equations…

1)Set the quadratic equation equal to zero (make sure terms are in proper standard form) 2)Select the values of a, b, and c 3)Place these values into the Quadratic Formula and then simplify to get your two solutions (“roots”) - attention to details! Procedure…

Let’s do some…

The discriminant…

How does the discriminant work?

Examples…
