expand (x^2+y^2)/((y-x)(y+x))

expand

\frac{x ^{2} + y ^{2}}{( y - x ) ( y + x )}

\frac{x ^{2} + y ^{2}}{y ^{2} - x ^{2}}

Solution steps

\frac{x ^{2} + y ^{2}}{( y - x ) ( y + x )}

Expand

(y - x) (y + x) : y^{2} - x^{2}

= \frac{x ^{2} + y ^{2}}{y ^{2} - x ^{2}}

(x^{2} - y^{2}) d x + x y^{2} d y

\frac{5 ( 8 + x )}{2}

\frac{x + 1}{( x + 2 ) ( x ^{2} + 2 s + 5 )}

3 x^{2} (3 x)
