expand (-2x^2-2x+2)/((x^2+1)^2)

expand

\frac{- 2 x ^{2} - 2 x + 2}{( x ^{2} + 1 ) ^{2}}

\frac{- 2 x ^{2} - 2 x + 2}{x ^{4} + 2 x ^{2} + 1}

Solution steps

\frac{- 2 x ^{2} - 2 x + 2}{( x ^{2} + 1 ) ^{2}}

(x^{2} + 1)^{2} = x^{4} + 2 x^{2} + 1

= \frac{- 2 x ^{2} - 2 x + 2}{x ^{4} + 2 x ^{2} + 1}
