Select the equation that would graph the parabola.

• y = -1/2x² + 2x+ 6

• y = 1/2x ² +2x-6

• y = -1/2x² - 2x + 6

• y = 1/2x² -2x -6

Factor the equation:

16x² - 9 = 0?

• (16x+3) (16x-3)

• (4x+3) (4x-3)

• (16x-3) (16x-3)

• (4x+3) (4x+3)

Solve by taking square roots:

5b² - 4 = 41

• b = 9, b = -9

• b = 3, b = -3

• b = 8, b = -8

• no real solution
