Question

integral (x+7)^2 dx

Answer 1

I don't think there is a substitution that can help you.
Just multiply it out and integrate it. :D
\[\int x^2 + 14x + 49 dx\]

Answer 2

\[\frac{ x^3 }{ 3 } + 7x^2 + 49x ?\]

Answer 3

Not quite.
Don't forget the \(+ C\)!

Answer 4

is it right if i add the +C?
Do I need to factor it more?

Answer 5

It's right if you add the C.
You can factor out an x but I don't think it matters much either way.

Answer 6

alright thank you
