8 the coefficient of the squared term: 

Divide each side by '8'.
0.375 + 3x + x2 = 0

Move the constant term to the right:

Add '-0.375' to each side of the equation.
0.375 + 3x + -0.375 + x2 = 0 + -0.375

Reorder the terms:
0.375 + -0.375 + 3x + x2 = 0 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + 3x + x2 = 0 + -0.375
3x + x2 = 0 + -0.375

Combine like terms: 0 + -0.375 = -0.375
3x + x2 = -0.375

The x term is 3x.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3x + 2.25 + x2 = -0.375 + 2.25

Reorder the terms:
2.25 + 3x + x2 = -0.375 + 2.25

Combine like terms: -0.375 + 2.25 = 1.875
2.25 + 3x + x2 = 1.875
