Which value of x would make a polynomial equal to zero if the factors of the polynomial were (x+3) and (x+12)

-3, -12

Step-by-step explanation:

Values of x which make the polynomial equal to 0 are called the roots or x-intercepts of the function. To find these values, set each factor equal to 0.

(x+3)=0

x=-3

(x+12)=0

x=-12

unless if u could do my questions, if not i wouldn't want to
