The problem is ∫x^2 - 3x - 5 with the lower limit being -4 and the upper limit 7.

I broke the integrals into three parts from [-4, -1.1926], [-1.1926, 4.1926], [4.1926, 7]

I did the integral and got (x^3)/3 - (3/2)x^2 - 5x

I subbed in the lower and upper limits and got 32.861 for [-4, -1.1926], 15.231 for [-1.1926, 4.1926], and finally 28.957 for [4.1926, 7].

I don't necessarily need a step by step solution ( though it would be greatly appreciated). I would really just like to know if you can spot which/where I am getting the wrong value(s).

EDIT: The final answer I keep getting is 76.691. The answer I get when I use a definite integral calculator is 83.2233
