Answer 2

Answer:

c. 14

Step-by-step explanation:

2+√3/2-√3 + 2-√3/2+√3

⬇                     ⬇

A                    B

A = 2+√3/2-√3 = 2+√3*2+√3/2-√3*2+√3 = 4+ 4√3 + 3/4-3 = 7+ 4√3/1= 7+ 4√3

B = 2-√3/2+√3 = 2-√3*2-√3/2+√3*2-√3 = 4- 4√3 + 3/4-3 = 7-4√3/1= 7- 4√3

2+√3/2-√3 + 2-√3/2+√3

=A+B

=7+ 4√3 + 7- 4√3

=14 (+ 4√3 and - 4√3 get cancelled)
