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

expand

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

\frac{1}{x ^{4} + a ^{2} x ^{2}}

Solution steps

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

Expand

x^{2} (x^{2} + a^{2}) : x^{4} + a^{2} x^{2}

= \frac{1}{x ^{4} + a ^{2} x ^{2}}

(x y + z) (x y - z)

(4 \cdot sin (6 \cdot π \cdot t) + cos (80 \cdot π \cdot t))^{2}

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

U (t - 2 π)

e^{4 (4 - 9 s i n^{2} (t))}
