Let rehman age be x
so acc to question
1/(x-3)+ 1/x+5 =1/3
((x+5)+(x-3))/(x-3 )(x+5)=1/3
(2x+2)/xsquare +2x-15=1/3
6x+6=xsquare +2x -15
xsquare -4x-21=0
xsquare -7x+3x-21=0
x(x-7)+3 (x-7)
x=7 x=-3
age can't be negative so rehman age is 7 years
quadratic equation is very easy bro if you got equation
