expand-2/(3(x^2+4)(x^2+9))

expand

- \frac{2}{3 ( x ^{2} + 4 ) ( x ^{2} + 9 )}

- \frac{2}{3 x ^{4} + 39 x ^{2} + 108}

Solution steps

- \frac{2}{3 ( x ^{2} + 4 ) ( x ^{2} + 9 )}

Expand

3 (x^{2} + 4) (x^{2} + 9) : 3 x^{4} + 39 x^{2} + 108

= - \frac{2}{3 x ^{4} + 39 x ^{2} + 108}

\frac{2.4 + 0.7}{0.5} - \frac{3.6}{1.6}

\frac{d}{d x} ((f (x, y)) (3 x y - 4)^{2})

\frac{1}{( x - 1 ) ( x - 3 ) ( 7 x ^{2} + 6 x + 1 )}

cos (x + y) d x + (3 y^{2} + 2 y + cos (x + y)) d y

\frac{s ^{2} ( 2 s ^{2} + 1 )}{( 8 s ^{2} + 9 s + 2 ) ( s ^{3} + 1 )}
