Solve the equation by factoring and using zero product property:

x² - 6x - 40 = 0

• x = -10; x = 4

• x = 10; x = -4

• x = 10; x = 4

• x = -10; x = -4

Factor and Solve: 3w² + 14w + 8 = 0

• w = 4 and 2/3

• w = -2/3 and -4

• w = 2/3 and -4

• w = 4 and -2/3

Factor and Solve: f(x) = x² + x - 42

• 7 and -6

• 1 and 42

• -7 and 6

• 8 and -3
