Have you tried completing the square inside the square root first?

This might end up being a trig sub.

i will be back if you have questions

yeah i tried it.. but that didnt worked !

u can take (x-1) as u and the rest term as v and integrate by parts

@ikram002p please help !

addy :o
is it like this ?
\(\int (x-1) \sqrt (1-x-x^2)\)

yeah exactly!

The trig sub seems to work
Not saying there aren't other ways though

to what integral have you transformed it?

i could not figure out anything

can you tell me what substitutions you performed ?

some people like to do two here
i just like one

I'm confused

did you complete the square inside the square root part?

Oh I'm sorry I didn't know you couldn't do the algebra either

So by nothing means absolutely nothing
I get it
