expand 2/((x^2+2)(x^2+1))

expand

\frac{2}{( x ^{2} + 2 ) ( x ^{2} + 1 )}

\frac{2}{x ^{4} + 3 x ^{2} + 2}

Solution steps

\frac{2}{( x ^{2} + 2 ) ( x ^{2} + 1 )}

Expand

(x^{2} + 2) (x^{2} + 1) : x^{4} + 3 x^{2} + 2

= \frac{2}{x ^{4} + 3 x ^{2} + 2}

(x + 3 + 1)^{2}

A (3, - 2) B (5, 4)

(t e^{(- 2 t)} + sin (t) + cos (t))^{2}

(x + 2 y) d y

(2 cos (t) - 2 - 2 sin (t))^{2}
