Solving for variable 'X'.

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

Divide each side by '2'.
1.5 + -3X + X2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + -3X + -1.5 + X2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + -3X + X2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + -3X + X2 = 0 + -1.5
-3X + X2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
-3X + X2 = -1.5

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 = -1.5 + 2.25

Reorder the terms:
2.25 + -3X + X2 = -1.5 + 2.25

Combine like terms: -1.5 + 2.25 = 0.75
2.25 + -3X + X2 = 0.75

Factor a perfect square on the left side:
(X + -1.5)(X + -1.5) = 0.75

Calculate the square root of the right side: 0.866025404
