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

expand

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

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

Solution steps

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

Expand

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

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

(x + 6 - 9 x + 70)^{2}

x \cdot (1 - e^{- \frac{1}{x}})

(x + 5 - 3) (x^{2} + 9 + 5)

sin (a) (csc (a) - sin (a))

(1 + 2 y i)^{2}
