Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.035' to each side of the equation.
0.035 + 0.21x + -0.035 + x2 = 0 + -0.035

Reorder the terms:
0.035 + -0.035 + 0.21x + x2 = 0 + -0.035

Combine like terms: 0.035 + -0.035 = 0.000
0.000 + 0.21x + x2 = 0 + -0.035
0.21x + x2 = 0 + -0.035

Combine like terms: 0 + -0.035 = -0.035
0.21x + x2 = -0.035

The x term is 0.21x.  Take half its coefficient (0.105).
