Best ResponseYou've already chosen the best response.0if 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.

Best ResponseYou've already chosen the best response.0Then, consider what would have to be added to the right side to keep both sides equal.

Best ResponseYou've already chosen the best response.0Right, adding 4 inside the parentheses on the left yields \(\large 3(g^24g+4)=4 + ?\)

Best ResponseYou've already chosen the best response.0What happens when you distribute that 3 back into those parentheses on the left?

Best ResponseYou've already chosen the best response.0Right, so you actually added 12 to both sides to complete the square. \(\large 3g^2−12g+12)=−4+12\). See?
