1. ## integration

hi,

i need to know how to integrate this:

(integrate sign with 2 at top and -2 at bottom) 6x^2+1 dx

i know how to start it:

=[6x^3/3+x] (2 at top of bracket, -2 at bottom)

but its after this im stuck. im not sure how to simplify 6x^3/3?
after this part i cant do i should be able to complete it but im not sure how to simplify it.
You're just expected to use the fact that $\frac{6}{3}=2$.
