emily require x hours
Max requires x+5
..
emily can do the 1/x of the job in 1 hour
max can do 1/(x+5) of the job in 1 hour
..
Together they will do in hours
LCM = x(x+5)

find the roots of the equation x1,x2 using quadratic equation

x1= 0.17 hours --- Emily does it in 0.17 hours
x2= -4.8 hours ignore this value
