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

Divide each side by '-2'.
5 + -1.5x + x2 = 0

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -1.5x + -5 + x2 = 0 + -5

Reorder the terms:
5 + -5 + -1.5x + x2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -1.5x + x2 = 0 + -5
-1.5x + x2 = 0 + -5

Combine like terms: 0 + -5 = -5
-1.5x + x2 = -5

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 = -5 + 0.5625

Reorder the terms:
0.5625 + -1.5x + x2 = -5 + 0.5625

Combine like terms: -5 + 0.5625 = -4.4375
0.5625 + -1.5x + x2 = -4.4375

Factor a perfect square on the left side:
(x + -0.75)(x + -0.75) = -4.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
