Question

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

Answer 1

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

Answer 2

this may involve imaginary numbers

Answer 3

multiply by \(\huge \frac{\sqrt{-x-1}}{\sqrt{-x-1}}\)

Answer 4

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

Answer 5

darn it latex lol

Answer 6

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

Answer 7

but does it still need simplified further?

Answer 8

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

Answer 9

has your teacher gone over imaginary numbers?

Answer 10

\[6x \sqrt{x-1}\div-x-1\] 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.

Answer 11

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

Answer 12

needed*

Answer 13

thanks!
