Equation will be x/2+2√x+6=x
⇒x/2-2√x=6
⇒x-4√x=12
⇒(√x-2)²=12+4
⇒(√x-2)²=4²
whether √x-2=4
or √x-2=-4
so x=36,4 ans

Let total no. of employees = x
now, twice the square root of the number of the employees = 2√x
half the number = x/2
remaining =6
so the equation will be
2√x + x/2 +6 =x
squarring both sides
16x = x^2 -24x +144
x^2 -40x +144=0
(x-36)(x-4)=0
now x= 4 is not possible as total no. of employees cant be < 6
so total no. of employes = 36
