expand-(4(-4s^2+1))/((4s^2+1)^2)

expand

- \frac{4 ( - 4 s ^{2} + 1 )}{( 4 s ^{2} + 1 ) ^{2}}

- \frac{- 16 s ^{2} + 4}{16 s ^{4} + 8 s ^{2} + 1}

Solution steps

- \frac{4 ( - 4 s ^{2} + 1 )}{( 4 s ^{2} + 1 ) ^{2}}

(4 s^{2} + 1)^{2} = 16 s^{4} + 8 s^{2} + 1

= - \frac{4 ( - 4 s ^{2} + 1 )}{16 s ^{4} + 8 s ^{2} + 1}

Expand

4 (- 4 s^{2} + 1) : - 16 s^{2} + 4

= - \frac{- 16 s ^{2} + 4}{16 s ^{4} + 8 s ^{2} + 1}

0^{2} + \frac{x}{2} - (- \frac{x}{2} - 10 = 0)

(9 x + 27) (9 y - 9)^{^{'}}

\frac{1}{( x - h ) ^{3}}

(- 3 x^{2} + 12 x - 8) - (x^{2} - 4 x + 4) d x

8^{(2 v^{2} - v)^{7}}
