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

expand

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

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

Solution steps

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

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

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

\frac{( 1 - 2 x ) π}{x - 1}

\frac{3 ( x + h ) + 4 - 3 x + 4}{h}

f (+ 5, - 1)

- e^{t} - (1 + x e^{x}) e^{x}
