if you factor out the 3 on the left, you'll get \(\large 3(g^24g)=4\) Then to complete the square, add the square of half the coefficient of g.

Then, consider what would have to be added to the right side to keep both sides equal.

Right, adding 4 inside the parentheses on the left yields \(\large 3(g^24g+4)=4 + ?\)

What happens when you distribute that 3 back into those parentheses on the left?

Right, so you actually added 12 to both sides to complete the square. \(\large 3g^2−12g+12)=−4+12\). See?
