Strategy:	1. Rewrite the equation with just the variable terms on the left. 2. Complete the square on the left side. 3. Extract square roots from both sides. 4.Solve the equation.
9(y² - 4y) = -5 9(y² - 4y + ___) = -5 + ___	Rewrite the equation with just the variable terms on the left. Add the same number to both sides so as to make the left side a perfect square.
^{Show work.}	This is done by taking half the coefficient of the linear term (i.e. half of 4), squaring that number, multiply it by the coefficient 9 and then adding that product to both sides.
