Could someone please help step by step in clear hand writing to teach me how to do this? So far, I ended up getting integral with a lower bound of 4 and upper bound of 9, but I see that in none of the options. How would I do this with u = sqrt(x + 2)? Thank you.

Using the substitution u = vx+2, [, xvx + 2 ax is equal to which of the following? O 2/, u du 02 / (u" - 2u? ) du 0 2/, (4 - 2u? ) du
