expand (3x^4+5)/((x^2+1)^2)

expand

\frac{3 x ^{4} + 5}{( x ^{2} + 1 ) ^{2}}

\frac{3 x ^{4} + 5}{x ^{4} + 2 x ^{2} + 1}

Solution steps

\frac{3 x ^{4} + 5}{( x ^{2} + 1 ) ^{2}}

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

= \frac{3 x ^{4} + 5}{x ^{4} + 2 x ^{2} + 1}

\frac{a}{( 2 - bi ) ^{2}}

x \cdot (1 - \frac{1}{x ^{2}})

\frac{( x - 3 ) ^{2}}{2}

10 δ (x - 5 π) + y

f (x) - x (x - 9 x)
