Numerical answer [src]

x/(y - x) + y/(x - y)

x/(y - x) + y/(x - y)

Rational denominator [src]

x*(x - y) + y*(y - x)
---------------------
   (x - y)*(y - x)

$$\frac{x \left(x - y\right) + y \left(- x + y\right)}{\left(- x + y\right) \left(x - y\right)}$$

(x*(x - y) + y*(y - x))/((x - y)*(y - x))

Combining rational expressions [src]

x*(x - y) + y*(y - x)
---------------------
   (x - y)*(y - x)

$$\frac{x \left(x - y\right) + y \left(- x + y\right)}{\left(- x + y\right) \left(x - y\right)}$$

(x*(x - y) + y*(y - x))/((x - y)*(y - x))
