Dear student 
Multiply and divide with conjugate base function. 
we get , √{(x+a)(x+b)} – x  *  √{(x+a)(x+b)} +x   /   √{(x+a)(x+b)} + x
= (ax + bx) / √{(x+a)(x+b)} + x
Take x common from numerator and denominator 
and apply the limit 
Ans will be (a+b)
Hope this helps 
Good Luck

Dear student 
The ans for the above question will be (a+b)/2 because in denominator after taking x common the term left would be 2. 
Hope this helps 
Good Luck
