Find the Zeros of the Polynomial Using Factors

If x-2 is a factor of x^2+5x+7, then that means.....

• f(0) = 2

• f(0) = -2

• f(2) = 0

• f(-2) = 0

Find the zeros of the polynomial.

Hint: (x-2) is a factor

First do the list of P/Q, then test the possible rational zeros using SYNTHETIC DIVISION, then find the remaining zeros

• A

• B

• C

• D
