Doh. That'll do it. Thanks.
This is a refresher for me why don't you have to multiply the denominator by the other two denominators?
Because $\displaystyle x^2+1$ is already a factor of $\displaystyle (x^2+1)^2$, so the LCD is just $\displaystyle x(x^2+1)^2$ as opposed to $\displaystyle x(x^2+1)(x^2+1)^2$
