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

Divide each side by '2'.
-91 + 1.5x + x2 = 0

Move the constant term to the right:

Add '91' to each side of the equation.
-91 + 1.5x + 91 + x2 = 0 + 91

Reorder the terms:
-91 + 91 + 1.5x + x2 = 0 + 91

Combine like terms: -91 + 91 = 0
0 + 1.5x + x2 = 0 + 91
1.5x + x2 = 0 + 91

Combine like terms: 0 + 91 = 91
1.5x + x2 = 91

The x term is 1.5x.  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.
1.5x + 0.5625 + x2 = 91 + 0.5625

Reorder the terms:
0.5625 + 1.5x + x2 = 91 + 0.5625

Combine like terms: 91 + 0.5625 = 91.5625
0.5625 + 1.5x + x2 = 91.5625
