expand (-3x^4+1)/((x^4+1)^2)

expand

\frac{- 3 x ^{4} + 1}{( x ^{4} + 1 ) ^{2}}

\frac{- 3 x ^{4} + 1}{x ^{8} + 2 x ^{4} + 1}

Solution steps

\frac{- 3 x ^{4} + 1}{( x ^{4} + 1 ) ^{2}}

(x^{4} + 1)^{2} = x^{8} + 2 x^{4} + 1

= \frac{- 3 x ^{4} + 1}{x ^{8} + 2 x ^{4} + 1}

\int (sec^{3} (3 x)) (tan (3 x)) d x

\int 5 t sin (t) cos (t) d t

\int (\frac{x}{1 + x ^{4}}) d x

\int \frac{1}{25 x ^{2} + 36} d x

\frac{d}{d x} (m x^{m - 1})
