Can someone explain this? Integral from 10 to 13 of 2x? It's been a long time since calculus for me, but isn't that like 2x² + c or something like that?

Never heard of this before, looks cool. Wish I had that when I was taking calculus lol

Just x²+c, but when you're integrating between limits the +c doesn't matter - so you're just left with the difference between 13² and 10²...

The integral of 2xdx is x^2 + c, and it’s evaluated from 10 to 13. So you’d have the following:

(13^2 + c) - (10^2 + c).

The c’s cancel. I’ll leave you to do the rest…
