12 + -1x + 5x2 = 0

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

Divide each side by '5'.
2.4 + -0.2x + x2 = 0

Move the constant term to the right:

Add '-2.4' to each side of the equation.
2.4 + -0.2x + -2.4 + x2 = 0 + -2.4

Reorder the terms:
2.4 + -2.4 + -0.2x + x2 = 0 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + -0.2x + x2 = 0 + -2.4
-0.2x + x2 = 0 + -2.4

Combine like terms: 0 + -2.4 = -2.4
-0.2x + x2 = -2.4

The x term is -0.2x.  Take half its coefficient (-0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
-0.2x + 0.01 + x2 = -2.4 + 0.01

Reorder the terms:
0.01 + -0.2x + x2 = -2.4 + 0.01

Combine like terms: -2.4 + 0.01 = -2.39
0.01 + -0.2x + x2 = -2.39

Factor a perfect square on the left side:
(x + -0.1)(x + -0.1) = -2.39

Can't calculate square root of the right side.
