Integrate from x=-1 to x=3,
A=int%28%28%284x%2B2%29-%28x%5E2%2B2x-1%29%29%2Cdx%2Cx=-1%2C3%29
A=int%28%28-x%5E2%2B2x%2B3%29%2Cdx%2Cx=-1%2C3%29
A=-x%5E3%2F3%2Bx%5E2%2B3x%2BC
A=-3%5E3%2F3%2B3%5E2%2B3%283%29-%28-%28-1%29%5E3%2F3%2B%28-1%29%5E2%2B3%28-1%29%29
A=-27%2F3%2B9%2B9%2B%28-1%2F3-1%2B3%29
A=-27%2F3%2B54%2F3-1%2F3-3%2F3%2B9%2F3
A=32%2F3

So for your definition of there are two seemingly equally likely causes of the obvious typographical error. Either you mistakenly held down the Shift key when you purposefully hit the underscore/dash key meaning to type a minus, or you purposefully held the shift key and mistakenly hit the underscore/dash key which is next to the plus/equals key meaning to type a plus.

Re-post your problem with understandable function definitions, and we would be delighted to help you. Hint: Proofread your posts BEFORE you hit send.
