Question

$\int \frac{1}{\left(x^2+a^2\right)\left(x^2+b^2\right)} d x=$

Accepted Answer

$\frac{1}{\left(a^2-b^2ight)}\left[\frac{1}{b} 	an ^{-1}\left(\frac{x}{b}ight)-\frac{1}{a} 	an ^{-1}\left(\frac{x}{a}ight)ight]+c$

Answer

$\frac{1}{\left(b^2-a^2ight)}\left[\frac{1}{b} 	an ^{-1}\left(\frac{x}{b}ight)-\frac{1}{a} 	an ^{-1}\left(\frac{x}{a}ight)ight]+c$

Answer

$\frac{1}{b} 	an ^{-1}\left(\frac{x}{b}ight)-\frac{1}{a} 	an ^{-1}\left(\frac{x}{a}ight)+c$

Answer

$\frac{1}{a} 	an ^{-1}\left(\frac{x}{a}ight)-\frac{1}{b} 	an ^{-1}\left(\frac{x}{b}ight)+c$
