          √3 - 1 
⇒  --------------------  = a + b√3
           √3 + 1

By multiplying numerator and denominator of L.H.S by ( √3 - 1 ) .

    ( √3 + 1 ) ( √3 + 1 )
⇒ ---------------------------------   =  a + b√3
       ( √3 + 1 ) ( √3 - 1 )


     (√3)² + 1 + 2 × √3 
⇒  --------------------------  = a + b√3
           (√3)² - 1²

     3 + 1 + 2√3 
⇒ --------------------  = a + b√3
        3 - 1

       4 + 2√3 
⇒  ------------------ = a + b√3
           2

     2 ( 2 + √3 )
⇒  ------------------ a + b√3
               2

⇒ 2 + √3 = a + b√3

By comparing coefficients,

 a = 2 and b = 1






Hope it helps !
