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

Divide each side by '2'.
-94.5 + 3x + x2 = 0

Move the constant term to the right:

Add '94.5' to each side of the equation.
-94.5 + 3x + 94.5 + x2 = 0 + 94.5

Reorder the terms:
-94.5 + 94.5 + 3x + x2 = 0 + 94.5

Combine like terms: -94.5 + 94.5 = 0.0
0.0 + 3x + x2 = 0 + 94.5
3x + x2 = 0 + 94.5

Combine like terms: 0 + 94.5 = 94.5
3x + x2 = 94.5

The x term is 3x.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3x + 2.25 + x2 = 94.5 + 2.25

Reorder the terms:
2.25 + 3x + x2 = 94.5 + 2.25

Combine like terms: 94.5 + 2.25 = 96.75
2.25 + 3x + x2 = 96.75
