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

expand

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

\frac{3 x ^{2} + 5}{x ^{4} + 8 x ^{2} + 16}

Solution steps

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

(x^{2} + 4)^{2} = x^{4} + 8 x^{2} + 16

= \frac{3 x ^{2} + 5}{x ^{4} + 8 x ^{2} + 16}

\frac{m x ^{m + 1} - ( m + 4 ) x ^{m - 1} + 10}{x - 1}

\frac{( 19 u + 4 ) ^{2}}{361}

\frac{2 x}{( 0.02 - x ) ^{2}}

- \frac{π}{30} sin (\frac{π}{90} (x + 20))

- \frac{( x - 2 ) ^{2}}{( x - 5 ) ^{2} ( x + 5 )}
