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

expand

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

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

Solution steps

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

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

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

\frac{( 3 x + 4 ) ^{3}}{9}

U (t - 4) (2 - t^{2}) + 3 e^{- π t} + sin (5 t) - t^{3}

9 (π + 1)

(A + B) (C + B) (D^{^{'}} + B) (A C D^{^{'}} + E)

(2 x + 3) d x + (3 x + 2 y) d y
