Answer:
A) (-9/7,0), (3/8,0)
Step-by-step explanation:
Zeros of a quadratic function:
x for which y = 0.
In this question:
It's 0 if one of the factors is 0. 6 is never 0, now about the other to:
So (-9/7, 0) is a zero of the quadratic function.
The other is:
(3/8,0) is the other zero.
Thus, the correct answer is given by option A.
