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

Divide each side by '10'.
0.7 + -0.2x + x2 = 0

Move the constant term to the right:

Add '-0.7' to each side of the equation.
0.7 + -0.2x + -0.7 + x2 = 0 + -0.7

Reorder the terms:
0.7 + -0.7 + -0.2x + x2 = 0 + -0.7

Combine like terms: 0.7 + -0.7 = 0.0
0.0 + -0.2x + x2 = 0 + -0.7
-0.2x + x2 = 0 + -0.7

Combine like terms: 0 + -0.7 = -0.7
-0.2x + x2 = -0.7

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 = -0.7 + 0.01

Reorder the terms:
0.01 + -0.2x + x2 = -0.7 + 0.01

Combine like terms: -0.7 + 0.01 = -0.69
0.01 + -0.2x + x2 = -0.69

Factor a perfect square on the left side:
(x + -0.1)(x + -0.1) = -0.69

Can't calculate square root of the right side.
