      You'll get the most benefit out of the questions if you attempt to find the solution steps yourself. Often the biggest hurdle in solving a problem is working out what to do; the execution is straightforward.

      I understand the first part as to simplify:

      (2-x)x^1/2
      but do I multiply both 2-x by the x^1/2 or just the x in the bracket, once I know that I can do it.

        The usual rules for brackets apply: (2-x)x^{1/2} = 2x^{1/2} - xx^{1/2}

        note that \int(f(x)+g(x)) dx = \int(f(x))dx + \int(g(x))dx
