x2/(-x) = -x.
I think you've left out something. Is one of the "x" functions squared?
8 + X SQUARED
(x2 - y2)/(x - y) = (x + y)(x - y)/(x - y) = x + y

The expression 3X divided by X squared can be simplified by dividing the coefficient of X by the coefficient of X squared. In this case, 3X divided by X squared simplifies to 3/X. This is because when dividing by a term with an exponent, you subtract the exponents in the denominator from the exponents in the numerator.
x2 divided by x would simply be x.
x-1
Your expression is this... x2 + y2/x
x2/(-x) = -x.
