B
x = -2
CX=0
[D] x=2
E
x = 9
7

Answer 1

The zeros of the function f(x) = (x - 2) (x + 9) are x = 2 and x = -9.

Step-by-step explanation:

The function f(x) = (x - 2) (x + 9) can be rewritten as f(x) = x^2 + 7x - 18. To find the zeros of the function, we set f(x) equal to zero and solve for x. So, x^2 + 7x - 18 = 0. We can solve this quadratic equation using factoring, completing the square, or the quadratic formula. In this case, by factoring, we can rewrite the equation as (x - 2) (x + 9) = 0. So, the two zeros are x = 2 and x = -9. Therefore, the correct options are (D) x = 2 and (A) x = -9.
