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

expand

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

\frac{2 y ^{2} - 2 x ^{2}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

Solution steps

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

(x^{2} + y^{2})^{2} = x^{4} + 2 y^{2} x^{2} + y^{4}

= \frac{2 y ^{2} - 2 x ^{2}}{x ^{4} + 2 y ^{2} x ^{2} + y ^{4}}

\frac{4 - e ^{- t}}{( e ^{- t} + 1 ) ( e ^{- t} + 2 )}

\frac{\partial}{\partial y} ((x) (y^{4} + 3 y - 4 x^{3} - 5 x))

(p + Δ p)^{2}

\frac{( 2 - x ) ^{4}}{16}

\frac{( n + 2 ) !}{( n + 1 ) !}
