Step by step solution :
Step  1  :
Pulling out like terms :
 1.1     Pull out like factors :
   2e + 4  =   2 • (e + 2)  
Equation at the end of step  1  :
Step  2  :
Equations which are never true :
 2.1      Solve :    2   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
 2.2      Solve  :    e+2 = 0  
Subtract  2  from both sides of the equation :  
                      e = -2

Answer:
c(x)=(x+3)^2+5
Step-by-step explanation:
To complete the square, the same value needs to be added to both sides.
So, to complete the square x^2+6x+9=(x+3)^2 add 9 to the expression
C(x) =x^2 +6x + 9 + 14
Since 9 was added to the right-hand side also add 9 to the left-hand side 
C(x) +9= x^2 +6x + 9 + 14
Using a^2 + 2ab + b^2=(a+b)^2, factor the expression
C(x)+9= (x+3)^2 +14
Move constant to the right-hand side and change its sign
C(x)=(x+3)^2 +14 - 9
Subtract the numbers
C(x)= (x+3)^2 +5
