What did I do wrong? -Calc. Substitution- Problem: [2-1<-- (this is from x=2 to x=1) x(x-1)^1/2 dX My Answer and work: Substitute U for x-1 du/dx = 1 du=dx [2-1 x (u)^1/2 (x^2)/2 * (u^3/2)/(2/3) ]2-1 (1/2(2)^2 * (3/2)1^(3/2)) - (1/2(1)^2*(3/2)(0)^(3/2) This comes out to 1.5 but the answers in the back of the book say it is 16/15. Can someone show me where I went wrong and get me to the right answer?
