Hi, Curve: x(x+1)(x-2) Find the area between the interval: (-1 to 2) Answer: The first thing I did was to find the x-intercepts: x=0, x=-1 and x=2 I then integrated the curve. I got: (x4/4)-(x3/3)-(x2) I then found the area between 0 and -1 and the area between 0 and 2. I added the absolute of both areas and got 37/12. The book, however, claims it is 2.25. Can anyone help me please? Thanks!
