expand (-6x^4+2)/((x^4+1)^2)

expand

\frac{- 6 x ^{4} + 2}{( x ^{4} + 1 ) ^{2}}

\frac{- 6 x ^{4} + 2}{x ^{8} + 2 x ^{4} + 1}

Solution steps

\frac{- 6 x ^{4} + 2}{( x ^{4} + 1 ) ^{2}}

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

= \frac{- 6 x ^{4} + 2}{x ^{8} + 2 x ^{4} + 1}

(cos (θ) + tan (θ)) sin (θ)

(1 - 0) (1 - 0.5) (1 - 1.5) (1 - 2)

\frac{5}{4 ( \frac{5}{4 x} )}

(x - 1) ln (x - 1)

\frac{d x}{( x + a ) ( x + b )}
