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. In this case, the zeros are the values of x that make the quadratic expression equal to zero.
If (x + 4) and (x - 8) are the linear factors of the quadratic expression, then when x equals -4, the expression (x + 4) equals zero, and when x equals 8, the expression (x - 8) equals zero.
Therefore, the zeros of the quadratic function are -4 and 8.
The correct answer is b) -4 and 8.
