Question

What are the zeros of the polynomial function f(x)=x(x-4)(x+9)? HELP NEEDED!!!!

Answer 1

Answer: 0, 4, -9

Set the equation equal to zero.

x(x - 4)(x + 9) = 0

Solve for x by setting each factor equal to zero.

The factors in the equation are x, (x - 4), and (x + 9).

• x = 0

• (x - 4) = 0

        x = 4

• (x + 9) = 0

        x = -9

The zeros of the function are 0, 4, and -9.
