we get the equation
We have given that the function
for completing the squares , we have to add both sides the square of half of coefficient of x
So we add both sides
Or,
add both side 7.5 square in given equation
Therefore,we get the equation

Steps to solve:
(12x + 4) - 8 = 12
~Combine like terms
12x - 4 = 12
~Add 4 to both sides
12x = 16
~Divide 12 to both sides
x = 16/12 or x = 4/3
Best of Luck!
