You must have meant
x^2/(x-y) - y^2/(x-y)
= (x^2 - y^2)/(x-y) , you had a common denominator
= (x+y)(x-y)/(x-y) , difference of squares at the top
= x + y , x ≠ y
x^2/(x-y) - y^2/(x-y)
= (x^2 - y^2)/(x-y) , you had a common denominator
= (x+y)(x-y)/(x-y) , difference of squares at the top
= x + y , x ≠ y
