    integral problems

    evaluate integrals:

    I(0 to 3) abs(x-2) dx

    I x2/(sqrt(-x+3)*sqrt(x+3)) dx

    I 2/ (16-x2) to pwr of 5/2 dx

    I (5x-12)/(x2 - 4x) dx

    Hi

    \int_{0}^{3} |x-2|\:dx = \int_{0}^{2} |x-2|\:dx + \int_{2}^{3} |x-2|\:dx = \int_{0}^{2} (2-x) \:dx + \int_{2}^{3} (x-2)\:dx
