Divide each side by '32'.
-0.21875 + 1.5x + x2 = 0

Move the constant term to the right:

Add '0.21875' to each side of the equation.
-0.21875 + 1.5x + 0.21875 + x2 = 0 + 0.21875

Reorder the terms:
-0.21875 + 0.21875 + 1.5x + x2 = 0 + 0.21875

Combine like terms: -0.21875 + 0.21875 = 0.00000
0.00000 + 1.5x + x2 = 0 + 0.21875
1.5x + x2 = 0 + 0.21875

Combine like terms: 0 + 0.21875 = 0.21875
1.5x + x2 = 0.21875

The x term is 1.5x.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5x + 0.5625 + x2 = 0.21875 + 0.5625

Reorder the terms:
0.5625 + 1.5x + x2 = 0.21875 + 0.5625
