Integration help please!?

Posted by Саша 21:08, under | No comments

I have this question out of the textbook. The answer in the back is 84.43 but I got 85.28 - not sure where I have gone wrong. The question is as follows:

Use centre function values with strips 0.4 units wide to find approximations for:
(integration sign with values 1 and 5) (x^2+2x+5) dx
