5 the coefficient of the squared term: 

Divide each side by '5'.
0.358 + 0.32x + x2 = 0

Move the constant term to the right:

Add '-0.358' to each side of the equation.
0.358 + 0.32x + -0.358 + x2 = 0 + -0.358

Reorder the terms:
0.358 + -0.358 + 0.32x + x2 = 0 + -0.358

Combine like terms: 0.358 + -0.358 = 0.000
0.000 + 0.32x + x2 = 0 + -0.358
0.32x + x2 = 0 + -0.358

Combine like terms: 0 + -0.358 = -0.358
0.32x + x2 = -0.358

The x term is 0.32x.  Take half its coefficient (0.16).
Square it (0.0256) and add it to both sides.

Add '0.0256' to each side of the equation.
0.32x + 0.0256 + x2 = -0.358 + 0.0256

Reorder the terms:
0.0256 + 0.32x + x2 = -0.358 + 0.0256

Combine like terms: -0.358 + 0.0256 = -0.3324
0.0256 + 0.32x + x2 = -0.3324

Factor a perfect square on the left side:
(x + 0.16)(x + 0.16) = -0.3324
