Solving for variable 'a'.

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

Divide each side by '25'.
0.04 + -0.32a + a2 = 0

Move the constant term to the right:

Add '-0.04' to each side of the equation.
0.04 + -0.32a + -0.04 + a2 = 0 + -0.04

Reorder the terms:
0.04 + -0.04 + -0.32a + a2 = 0 + -0.04

Combine like terms: 0.04 + -0.04 = 0.00
0.00 + -0.32a + a2 = 0 + -0.04
-0.32a + a2 = 0 + -0.04

Combine like terms: 0 + -0.04 = -0.04
-0.32a + a2 = -0.04
