Since (3.6)²= 14.1376
         (5.41)²= 29.2681
then , 3.76 + 5.41 = 9.17
 
 14.1376 - 29.2681 / 9.17
= 15.1305 / 9.17
= 1.65

its simple,
assume a=3.6 and b=5.41..........
put variable in equation
(a)^2-(b)^2/(a+b)
we know that a^2-b^2=(a+b)(a-b)
hence
=(a+b)(a-b)/(a+b)
(a+b) will be cancel from denominator and numerator
hence you will get
=a-b=3.76-5.41= -1.65
