Begin completing the square.  Divide all terms by
25 the coefficient of the squared term: 

Divide each side by '25'.
0.36 + 0.48x + x2 = 0

Move the constant term to the right:

Add '-0.36' to each side of the equation.
0.36 + 0.48x + -0.36 + x2 = 0 + -0.36

Reorder the terms:
0.36 + -0.36 + 0.48x + x2 = 0 + -0.36

Combine like terms: 0.36 + -0.36 = 0.00
0.00 + 0.48x + x2 = 0 + -0.36
0.48x + x2 = 0 + -0.36

Combine like terms: 0 + -0.36 = -0.36
0.48x + x2 = -0.36

The x term is 0.48x.  Take half its coefficient (0.24).
