Given that x=-2 is a zero of the function
f(x)=x^3+12x^2+5x-30

use synthetic division to help you find 
all of the other zeros.

All solutions must be exact - no approximate answers.

f(x) = x³ - 9x² - 45x - 27

Find the remaining zeros given that -3 is a zero of f(x).

• {-3, -6 ± 3√5}

• {-3, 6 ± 3√5}

• (-3, 3, 9}

• {-3, 0, 3}

If the binomial (x - 7) is a factor of the polynomial function f(x), which statement must be true?

• f(7) = -7

• f(7) = 0

• f(-7) = 0

• f(-7) = -7
