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

expand

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

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

Solution steps

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

Expand

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

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

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

2 (25 + 7)

\frac{1}{( s - 1 ) ( s - 2 ) ( s + 6 )}

- 2 \cdot (2 + 2 - 2)

(a + ib)^{2} + a + ib
