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

expand

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

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

Solution steps

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

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

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

sin (x) cos (x) (sec (x) + cot (x))

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

(1 + \frac{2}{3} x)^{6} (3 + 6 x)^{2}

sin^{2} (x) (1 + cos (x))

(1 + 3)^{5}
