X+√3/x-√3 + x+√5/x-√5
substitute the value of "x"
=> 2√15/√5+√3 +√3/2√15/√5+√3-√3 + 2√15/√5+√3+√5/2√15/√5+√3-√5

2√15+√15+3/√5+√3/2√15-√15-3/√5+√3 + 2√15+5+√15/√5+√3/2√15-5- √15/√5+√3

3√15+3/√15-3 + 3√15+5/√15-5

(√15-5)(3√15+3) + (√15-3)(3√15+5)/(√15-3)(√15-5)

45-15+3√15-15√15+45-15+5√15-9√15/30-5√15-3√15

60-16√15/30-8√15

2(30-8√15)/30-8√15

then the answer we get is 2
