Integration Technique

    I was working on a question and would this work?


    After I did all of the math, I got to:


    The problem I am having is not with the actual integration but another step I took:


    I figured that -1/3+c just makes another constant so I left it as:


    and distributing x^3 renders:


    Is this process correct?

    No problem combining constants, HOWEVER - Why did you take that other step (from 2nd equation to third)? That is, why do you think that other step is correct?

    I now realize I was wrong. I factored out an x^3 even though it didn't have one making my conclusion worthless.
