The linear factors of a quadratic expression are (x + 4) and (x - 8). What are the zeros of the related quadratic function?
a
4 and 8
b
4 and -8
c
-4 and -8
d
-4 and 8
The zeros of a quadratic function are the values of x that make the function equal to zero. Since the given linear factors are (x + 4) and (x - 8), the zeros of the related quadratic function are when x + 4 = 0 and when x - 8 = 0.
Solving these equations:
x + 4 = 0
x = -4
x - 8 = 0
x = 8
So, the zeros of the related quadratic function are x = -4 and x = 8.
Therefore, the answer is d) -4 and 8.
