(x+4)(2x+3)(-x-9)=f(x) find the zeros

9514 1404 393

  x = {-9, -4, -3/2}

Step-by-step explanation:

The zeros are the values of x that make the factors zero. (If a factor is zero, the product will be zero.)

x+4 = 0

  x = -4 . . . . subtract 4

2x+3 = 0

  2x = -3 . . . . subtract 3

  x = -3/2 . . .  divide by 2

-x-9 = 0

  -9 = x . . . . add x

__

The zeros are ...

  x = {-9, -4, -3/2}
