Quick question: is the following a correct integral formula?(adsbygoogle = window.adsbygoogle || []).push({});

$$\int \! \frac{1}{(-x + a)^2} dx = -\left(\frac{1}{-x + a}\right)$$

I couldn't find it on the integral tables, so I just extrapolated from a similar integral formula I've found there. That formula being:

$$\int \! \frac{1}{(x + a)^2} dx = -\left(\frac{1}{x + a}\right)$$

Now ladies and gentlemen...if my extrapolation was incorrect, would you be so generous as to provide me with the correct formula? Or share with me the proper methodology as to how to generate it, if my quick and dirty guesswork is inappropriate?
