2. Relevant equations

3. The attempt at a solutionI know from the web the answer is -x+1/2ln(2x+1)+C, but all I keep seeing for explanations is add and subtract 1 to the numerator and mysteriously you get an answer. I don't get it. Can somebody Please, Please, Please, explain, or point me to a site that helps to explain how to integrate this in detail? I just need something in english, not math language.
