I know that it is undefined at x=1 because the denominator can't be 0, so I did this:

+

Then I integrated it...

+

Plugging everything in-

- + -

Then I started to find the limit but somehow I got the wrong answer. I got 1.5-1.5+1.5-1.5 for some reason, because I got that the one sided limits go to 1.5. The answer is supposed to be3.

Thank you for your help!!
