zubhanwc3 · Answer

i found the indefinite integral to be $$2/5(2-x)^{3/2}(x+3) + C$$

zubhanwc3 · Answer

i dont know what to do, to solve for x

anonymous · Answer

umm.. from what i know, if you have found the integral, you don't need to solve for x nor can not

anonymous · Answer

You're missing a negative sign but in general you would break it up to:
$$\int x \sqrt{2-x}dx + \int \sqrt{2-x}dx$$
The second one is easy, the first one can be solved with integration by parts.
