how do you subtract these? negative square root of 3 over 2 - square root of 3 over 3

OpenStudy (anonymous):

time both numerator and denominator of the first fraction with 3 and the second with 2. Try it.

OpenStudy (anonymous):

depends. if you are talking about an unsimplified root first simplify the root by multiplying top and bottom with the certain root

OpenStudy (anonymous):

if you have sqrt(3/2), then multiply top and bottom by sqrt(2) you get sqrt(6)/2

OpenStudy (anonymous):

could be, not quite clear with the question

OpenStudy (anonymous):

I would assume -sqrt(3) sqrt(3) ------ - ------ 2 3 Correct?

OpenStudy (anonymous):

If so... you need a common denominator of 6 -3sqrt(3) 3sqrt(3) -------- - ------- 6 6 -6 sqrt(3) --------- 6 -sqrt(3) as the answer
