Answer:

Step-by-step explanation:
the quadratic function should be as follows:

Now let's confirm that the zeros of the function are 0 and 8

Therefore we can see that if x = 0

the equation is fulfilled
And we also have 
for this expresion to be equal to zero:

thus, if x = 8

the equation is also fulfilled
The zeros of the quadratic function
are 0 and 8.
