Divide each side by '4'.
0.25 + -0.25x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + -0.25x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + -0.25x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + -0.25x + x2 = 0 + -0.25
-0.25x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
-0.25x + x2 = -0.25

The x term is -0.25x.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25x + 0.015625 + x2 = -0.25 + 0.015625
