1. The problem statement, all variables and given/known data
I am trying to integrate from 0 to 10 ft -4x^2/2+4x. I am solving for deflection. The forces are in kips. Somehow the book ends up with k-ft^3. I don't understand how I would carry units in an integration. Any help please?

2. Relevant equations

Normally integrating gives an area which would give the product of the units on the axes. I'd be inclined to think you'd get kip-ft. Are you sure the units are correct?
