QUADRATIC FORMULA November 17, 2009

Objectives  Apply the quadratic formula  Use words to describe the process of the quadratic formula, verbally  Practice using the quadratic formula, in writing

1) x 2 -5x-14=0

2) x 2 -2x-35=0

3) t 2 +8t-65=0

4) q 2 +3q-130=0

5) 3x 2 +x-10=0

6) 3x 2 +2x-1=0  3x 2 +2x-1=0

7) 16t 2 -24t+9=0

8) 6m 2 -23m+10=0

What if the discriminant is negative? i = √-1 So, √-36= i √36=6i

4x 2 + 5x + 2 = 0

12x 2 + 4x + 5 = 0

9x x + 5 = 0

11x x + 4 = 0

5x 2 - 7x + 9 = 0
