9 + -12y + 8y2 = 0

Solving for variable 'y'.

Begin completing the square.  Divide all terms by
8 the coefficient of the squared term: 

Divide each side by '8'.
1.125 + -1.5y + y2 = 0

Move the constant term to the right:

Add '-1.125' to each side of the equation.
1.125 + -1.5y + -1.125 + y2 = 0 + -1.125

Reorder the terms:
1.125 + -1.125 + -1.5y + y2 = 0 + -1.125

Combine like terms: 1.125 + -1.125 = 0.000
0.000 + -1.5y + y2 = 0 + -1.125
-1.5y + y2 = 0 + -1.125

Combine like terms: 0 + -1.125 = -1.125
-1.5y + y2 = -1.125

The y term is -1.5y.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5y + 0.5625 + y2 = -1.125 + 0.5625

Reorder the terms:
0.5625 + -1.5y + y2 = -1.125 + 0.5625

Combine like terms: -1.125 + 0.5625 = -0.5625
0.5625 + -1.5y + y2 = -0.5625

Factor a perfect square on the left side:
(y + -0.75)(y + -0.75) = -0.5625

Can't calculate square root of the right side.
