expand (8x)/((5x^2+4)^2)

expand

\frac{8 x}{( 5 x ^{2} + 4 ) ^{2}}

\frac{8 x}{25 x ^{4} + 40 x ^{2} + 16}

Solution steps

\frac{8 x}{( 5 x ^{2} + 4 ) ^{2}}

(5 x^{2} + 4)^{2} = 25 x^{4} + 40 x^{2} + 16

= \frac{8 x}{25 x ^{4} + 40 x ^{2} + 16}

3 (3 - 17)

7 \times 5

sin (\frac{( 2 n - 1 ) π x}{2})

(t - sin (t)) (3 + 3 sin (t))

(3 + x) (2 + x)
