# C2 REALLY BASIC definite integral question, book has wrong answer? watch

1. Evaluate the definite integral of [1 - 2x - 3x^2 - 4x^3] limits: 3 on top, 2 on bottom.

integrating: x - x^2 - x^3 - x^4

-114--26 = -114 + 26 = -88.

2. Whatever the answer is, it's going to be a whole number. The book's definitely wrong there.
3. either the book is wrong or you've read something wrong,

If the book has 6 answers wrong then I think you are looking at the wrong chapter.
8. I get -88 also.

If the book has 6 answers wrong then I think you are looking at the wrong chapter.
I wouldn't rule that out at this stage
