Let Time period =T
Mass of the bob = m
Acceleration due to gravity = g
Length of string = L
Let 
⇒a=0 ⇒ Time period of oscillation is independent of mass of the bob
-2b=1
⇒b=-     
b+c = 0
- + c =0
c=
Giving values to a,b and c in first equation
The real expression for Time period is
Therefore time period of oscillation depends only on gravity and length of the string.
Not on mass of the bob.
