Solving for variable 'y'.

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
47 + -4.5y + y2 = 0

Move the constant term to the right:

Add '-47' to each side of the equation.
47 + -4.5y + -47 + y2 = 0 + -47

Reorder the terms:
47 + -47 + -4.5y + y2 = 0 + -47

Combine like terms: 47 + -47 = 0
0 + -4.5y + y2 = 0 + -47
-4.5y + y2 = 0 + -47

Combine like terms: 0 + -47 = -47
-4.5y + y2 = -47

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 = -47 + 5.0625

Reorder the terms:
5.0625 + -4.5y + y2 = -47 + 5.0625

Combine like terms: -47 + 5.0625 = -41.9375
5.0625 + -4.5y + y2 = -41.9375

Factor a perfect square on the left side:
(y + -2.25)(y + -2.25) = -41.9375

Can't calculate square root of the right side.
