Setting Quadratic Equation to zero
100

Solve for x:

2x = 14

x = 7

100

Manipulate the equation so that one side is zero:

x2 = 9

x- 9 = 0

200

Solve for y:

4y + 15 = 35

y = 5

200

Manipulate the equation so that one side is zero:

9y2 - 5 = 4y2 + 15

5y2 - 20 = 0

300

Solve for z:

6z + 12 = 3z + 24

z = 4
300

Manipulate the equation so that one side is zero:

14z2 + 6z + 2 = 11z2 + 5z + 5

3z+ z - 3 = 0
