Answer:
Quarter and a Nickel
Step-by-step explanation:
Sepecifically said ONE of them is not a quarter.
To simplify this expression you would factor out the greatest common factor which is y^2.
9y^2 - 11xy^2 -----> Factor out y^2
y^2(9 - 11x) ----> This should be as far as you can go, meaning this is your final answer!
Hope this helps!
