Answer:
   3
Step-by-step explanation:
For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...
   f(x) = ((x -2)x -7)x +5
and ...
   x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3
Then ...
   f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5
   = (3+2√3 -7)(2+√3) +5
   = 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5
   f(1/(2 -√3)) = 3
_____
If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.
