25 the coefficient of the squared term: 

Divide each side by '25'.
0.36 + 1.04x + x2 = 0

Move the constant term to the right:

Add '-0.36' to each side of the equation.
0.36 + 1.04x + -0.36 + x2 = 0 + -0.36

Reorder the terms:
0.36 + -0.36 + 1.04x + x2 = 0 + -0.36

Combine like terms: 0.36 + -0.36 = 0.00
0.00 + 1.04x + x2 = 0 + -0.36
1.04x + x2 = 0 + -0.36

Combine like terms: 0 + -0.36 = -0.36
1.04x + x2 = -0.36

The x term is 1.04x.  Take half its coefficient (0.52).
Square it (0.2704) and add it to both sides.

Add '0.2704' to each side of the equation.
1.04x + 0.2704 + x2 = -0.36 + 0.2704
