• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30

Convert to vertex form.

• y=-(x-5)² + 21

• y=-(x+5)² + 21

• y=-(x+10)² + 21

• y=-(x-10)² + 21

Solve by factoring OR using the quadratic formula:

x² + 7x - 93 = 7x + 7

• x = 0 and x = 100

• x = -10 and x = 10

• x = 0 and x = -100

• x = 10
