expand-(6(-3x^2+5))/((3x^2+5)^2)

expand

- \frac{6 ( - 3 x ^{2} + 5 )}{( 3 x ^{2} + 5 ) ^{2}}

- \frac{- 18 x ^{2} + 30}{9 x ^{4} + 30 x ^{2} + 25}

Solution steps

- \frac{6 ( - 3 x ^{2} + 5 )}{( 3 x ^{2} + 5 ) ^{2}}

(3 x^{2} + 5)^{2} = 9 x^{4} + 30 x^{2} + 25

= - \frac{6 ( - 3 x ^{2} + 5 )}{9 x ^{4} + 30 x ^{2} + 25}

Expand

6 (- 3 x^{2} + 5) : - 18 x^{2} + 30

= - \frac{- 18 x ^{2} + 30}{9 x ^{4} + 30 x ^{2} + 25}

(sin (\frac{3 t}{2}) + cos (\frac{3 t}{2}))^{2}

- ln (sin (x)) cos (x) + (- x - cot (x)) sin (x)

\frac{27 ( 4 - s ) ^{9}}{( - 4 s ^{3} + 48 s ^{2} - 192 s + 229 ) ^{3}}

(4 + i x)^{2}

- 2 (1 + 2)
