Evaluate \(\frac{2}{6-5\sqrt{3}}\)
\(-\left(\frac{12}{39}-\frac{10\sqrt{3}}{39}\right)\)
\(\frac{12}{39}-\frac{10\sqrt{3}}{39}\)
\(-\left(\frac{12}{39}+\frac{10\sqrt{3}}{39}\right)\)
\(\frac{12}{39}+\frac{10\sqrt{3}}{39}\)

the correct option is c
39 bears a negative sign and so when dividing the numerator
The correct option is C
Why?
we arrived at
(12+10√3) ÷ -39 ...this is equal to
(12 ÷ -39) + (10√3 ÷ -39) ....this means that every thing here is negative. i.e
(12 ÷ -39) + (10√3 ÷ -39) = -12/39 - (10√3)/39
It is the same as
-[(12÷39) +(10√3 ÷ 39)]
option c is very cornet, it is 35-75 =-39,definitely we should av an all negative fraction s
This is the right answer, pls let there be rectification of similar issues like this.

Please the answer is A.... Just like your workings showed, not C..... C is misleading.
