0 = 0.5x2 + 0.5x + 1.2

Reorder the terms:
0 = 1.2 + 0.5x + 0.5x2

Solving
0 = 1.2 + 0.5x + 0.5x2

Solving for variable 'x'.

Combine like terms: 0 + -1.2 = -1.2
-1.2 + -0.5x + -0.5x2 = 1.2 + 0.5x + 0.5x2 + -1.2 + -0.5x + -0.5x2

Reorder the terms:
-1.2 + -0.5x + -0.5x2 = 1.2 + -1.2 + 0.5x + -0.5x + 0.5x2 + -0.5x2

Combine like terms: 1.2 + -1.2 = 0.0
-1.2 + -0.5x + -0.5x2 = 0.0 + 0.5x + -0.5x + 0.5x2 + -0.5x2
-1.2 + -0.5x + -0.5x2 = 0.5x + -0.5x + 0.5x2 + -0.5x2

Combine like terms: 0.5x + -0.5x = 0.0
-1.2 + -0.5x + -0.5x2 = 0.0 + 0.5x2 + -0.5x2
-1.2 + -0.5x + -0.5x2 = 0.5x2 + -0.5x2

Combine like terms: 0.5x2 + -0.5x2 = 0.0
-1.2 + -0.5x + -0.5x2 = 0.0

Begin completing the square.  Divide all terms by
-0.5 the coefficient of the squared term: 

Divide each side by '-0.5'.
2.4 + x + x2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + x + -2.4 + x2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + x + x2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + x + x2 = 0 + -2.4
x + x2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
x + x2 = -2.4

The x term is x.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + x2 = -2.4 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = -2.4 + 0.25

Combine like terms: -2.4 + 0.25 = -2.15
1.25 + x2 = -2.15

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -2.15

Can't calculate square root of the right side.

The solution to this equation could not be determined.
