Studdy Solution
Now integrate each term separately:
(1x2+1x+2+1x1)dx \int \left( \frac{1}{x - 2} + \frac{1}{x + 2} + \frac{1}{x - 1} \right) dx
=1x2dx+1x+2dx+1x1dx = \int \frac{1}{x - 2} dx + \int \frac{1}{x + 2} dx + \int \frac{1}{x - 1} dx
Each integral is a natural logarithm:
=lnx2+lnx+2+lnx1+C = \ln|x - 2| + \ln|x + 2| + \ln|x - 1| + C
The solution to the integral is:
lnx2+lnx+2+lnx1+C \ln|x - 2| + \ln|x + 2| + \ln|x - 1| + C
