Which values of xwould make a polynomial equal to zero if the factors of the polynomial were (x+6) and (x+9)?
A. 6 and -9
B. -6 and 9
C. -6 and -9
D. 6 and 9

9514 1404 393

  C. -6 and -9

Step-by-step explanation:

For the polynomial to be zero, one or more of the factors must be zero. For the factors to be zero, we require ...

  x +6 = 0

  x = -6 . . . . . . subtract 6 from both sides of the equation

and likewise, ...

  x +9 = 0

  x = -9 . . . . . . subtract 9 from both sides of the equation

x = -6 or -9 will make the polynomial zero.
