Dividing Rational Expressions?

Question

(x^2-y^2/xy+x^2) divided by (y-x/x+y)

WOULD XY+X^2 BE THE CORRECT ANSWER???

Answer 1

Numerator , N
[ (x - y).(x + y) ] / [ x.(x + y) ]
= (x - y) / x
Denominator , D
(y - x) / (x + y)
= - (x - y) / (x + y)

N/D = - [(x - y) / x ].[ (x + y)/(x - y)]
N/D = - (x + y) / x
N/D = - 1 - y / x

Answer 2

rational expressions arnt that hard really. im tired do i frogot exactly how to do them but i know that if u got to google and type in
