why is the intergral of 16/(x^2)... -16/x?

what steps did you do for this? u substitution?

    Bring up the x^2 so you have the integral of 16x^-2. Put the 16 outside the integral sign so that you have only x^-2 inside the sign. Now follow the rules for integration- add 1 to -2 and the denomination of x^-2 has to have -2+1 also. You now have 16x^-1 over -1 which can be written as -16x^-1 which can be changed to -16/x

    You don't need u substitution for this one. You just use the regular rule for integrals, as follows:

    Integral of 16x^2 - 16x = 16 * x^3/3 - 16 * x^2/2 = (16x^3)/3 = 8x^2.

    16 / x^2 = 16(x^-2)

    Antiderivative would then be 16(x^(-2+1)) / (-2+1)

    16(x^-1) / -1

    -16 / x
