9 + -6.75y + 1.5y2 = 0

Solving for variable 'y'.

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

Divide each side by '1.5'.
6 + -4.5y + y2 = 0

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -4.5y + -6 + y2 = 0 + -6

Reorder the terms:
6 + -6 + -4.5y + y2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -4.5y + y2 = 0 + -6
-4.5y + y2 = 0 + -6

Combine like terms: 0 + -6 = -6
-4.5y + y2 = -6

The y term is -4.5y.  Take half its coefficient (-2.25).
Square it (5.0625) and add it to both sides.

Add '5.0625' to each side of the equation.
-4.5y + 5.0625 + y2 = -6 + 5.0625

Reorder the terms:
5.0625 + -4.5y + y2 = -6 + 5.0625
