8 + -3x + 2x2 = 0

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

Divide each side by '2'.
4 + -1.5x + x2 = 0

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -1.5x + -4 + x2 = 0 + -4

Reorder the terms:
4 + -4 + -1.5x + x2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1.5x + x2 = 0 + -4
-1.5x + x2 = 0 + -4
