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

Divide each side by '5'.
1.8 + -0.8x + x2 = 0

Move the constant term to the right:

Add '-1.8' to each side of the equation.
1.8 + -0.8x + -1.8 + x2 = 0 + -1.8

Reorder the terms:
1.8 + -1.8 + -0.8x + x2 = 0 + -1.8

Combine like terms: 1.8 + -1.8 = 0.0
0.0 + -0.8x + x2 = 0 + -1.8
-0.8x + x2 = 0 + -1.8

Combine like terms: 0 + -1.8 = -1.8
-0.8x + x2 = -1.8

The x term is -0.8x.  Take half its coefficient (-0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
-0.8x + 0.16 + x2 = -1.8 + 0.16

Reorder the terms:
0.16 + -0.8x + x2 = -1.8 + 0.16

Combine like terms: -1.8 + 0.16 = -1.64
0.16 + -0.8x + x2 = -1.64

Factor a perfect square on the left side:
(x + -0.4)(x + -0.4) = -1.64

Can't calculate square root of the right side.

The solution to this equation could not be determined.

This subproblem is being ignored because a solution could not be determined.
