Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.29' to each side of the equation.
0.29 + 0.4x + -0.29 + x2 = 0 + -0.29

Reorder the terms:
0.29 + -0.29 + 0.4x + x2 = 0 + -0.29

Combine like terms: 0.29 + -0.29 = 0.00
0.00 + 0.4x + x2 = 0 + -0.29
0.4x + x2 = 0 + -0.29

Combine like terms: 0 + -0.29 = -0.29
0.4x + x2 = -0.29

The x term is 0.4x.  Take half its coefficient (0.2).
