Question 1047401
The common denominator is 1/(3-4)=-1. That is the product of the two denominators, which have no internal products, only the first term squared + the second term squared.
Then the first term in the numerator is sqrt(3)-2, for that is the result of dividing sqrt(3)+2 into the common denominator of sqrt(3)+2*sqrt(3)-2.
The numerator is sqrt(3)-2+ sqrt(3)+2
This is 2 sqrt(3)
The answer is -2 sqrt(3)
