You're just expected to use the fact that .
Edit: I highly suggest revising your algebra skills before continuing with calculus because calculus will be an uphill struggle until your algebra skills are refined.
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.
could somone please help me on this part?!?
