    Finding Indefinite Integral

    (Integration symbol)((x^3)-3)^5 * x^3


    Totally confused on where to even begin...I think I can substitute u, but not sure...


    I think I solved it...

    (((x^4-3)^6)/24) + C

    Is that right?

    it is correct if the original integral was \int (x^4-3)^5 \cdot x^3 \, dx

    was that a typo above?

    If it was, in fact, \int (x^3-3)^5 x^3 dx, then the best way to integrate it is to multiply it out and integrate term by term.
