Answer:
i think 5 so i say pick 5 because 19no 12no10 no so it 5
The zeroes are (0,8) and (0,9)
Use the zero product property to find this
(x-8)=0
x=8
(x-9)=0
x=9
Subtract 88x from both sides. This will put all x coefficients on one side of the equation, and all constants on the other side, allowing her to easily find the value of x from there.
The equation would then become
