Intergrate 15x^2 + 7
Using the intergarting rules, you would add a power then divide that new number to the coefficent so you would get 5x^3 and just add one x to the 7 and dont forget the c. So the end answer would be 5x^3 + 7x + c and to make sure that you have the right answer you can always differentiate the answer you get to check.
