the intersection points on the graph are (-2,1) and (2,9)

i did: \[\int\limits_{-2}^{9} (x^2+2x+1-(2x+5))dx \] and I got 605/3. But now I'm starting to think I should have switched the functions. like:\[\int\limits_{-2}^{9} (2x+5)-(x^2+2x+1))dx\]

how did you get those pretty integer intersections? how did that one function magically appear?

I'm suppose to ignore that one function?

\[f(x)=x^2+2x+1 \] \[g(x)= 2x+5\]
