6x / sqrt(-x-1) rationalize the denominator

Question

anonymous · Answer

i got to -6x sqrt(-x-1) / -x-1 but i'm not sure how to simplify it after that

tylerd · Answer

this may involve imaginary numbers

xapproachesinfinity · Answer

multiply by $\huge \frac{\sqrt{-x-1}}{\sqrt{-x-1}}$

xapproachesinfinity · Answer

that should be root (-x-1) on top

darn it latex lol

anonymous · Answer

it would be $$-6\sqrt{x-1}\div-x-1$$

anonymous · Answer

but does it still need simplified further?

xapproachesinfinity · Answer

oh i didn't see you did that!
not what else can you do xD

tylerd · Answer

has your teacher gone over imaginary numbers?

anonymous · Answer

$$6x \sqrt{x-1}\div-x-1$$ but i know 6x and -x are like terms so i didn't know if I should divide them. and yes, but that's not what we're doing right now. it doesn't need simplified quite that far.

No no further operations need! that's the answer
@TylerD, what's the need for imaginary here!
I don't think so
