Answer:
x^2 - y^3 + y
Step-by-step explanation:
Simplify the following:
x^2 - (3 y^2 x y)/(3 x) + y
-(y^2 x×3 y)/(3 x) = 3/3×(-y^2 x y)/x = (-y^2 x y)/x:
x^2 + -(y^2 x y)/x + y
(-y^2 x y)/x = x/x×-y^2 y = -y^2 y:
x^2 + -y^2 y + y
-y^2 y = -y^(2 + 1):
x^2 + -y^(2 + 1) + y
2 + 1 = 3:
Answer: x^2 - y^3 + y
