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

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
substituting 3, answer is -114.
substituting 0, answer is -26.

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

books answer: 1/8

:confused:

Whatever the answer is, it's going to be a whole number. The book's definitely wrong there.
