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

expand

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

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

Solution steps

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

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

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

(x - 4 + 11) (x - 4 + 11)
