Solving for variable 'x'.

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

Divide each side by '2'.
-24 + 1.5x + x2 = 0

Move the constant term to the right:

Add '24' to each side of the equation.
-24 + 1.5x + 24 + x2 = 0 + 24

Reorder the terms:
-24 + 24 + 1.5x + x2 = 0 + 24

Combine like terms: -24 + 24 = 0
0 + 1.5x + x2 = 0 + 24
1.5x + x2 = 0 + 24

Combine like terms: 0 + 24 = 24
1.5x + x2 = 24

The x term is 1.5x.  Take half its coefficient (0.75).
