  1. Add the separate integrals of the two terms.
    The integral of x^4 dx is x^5/5.
    The integral of -6 x dx is -6*(1/2)x^2 = -3x^2.
    Add an arbitrary constant C to the sum.

    (x^5)/5 - 3 x^2 + C

  5. I know, but I don't see what you mean
    Is 5-3x^2 all under x^5

  6. No. 3x^2 and C are separate additive terms. As I said in the beginning, you add the integrals of each term.

  7. so, the answer would be like this

    (x^5/5)-3x^2+C
