The correct option is (A) -3 and -7
Explanation:
The factors tell us at which point the function or a polynomial will converge to zero. So to find that we put the factors equal to zero.
In the question given above the two factors are:
x+3 and x+7
Put both of them equals to zero!
x+3 = 0
x+7 = 0
=> x = -3
=> x = -7 (Option (A))
