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

Divide each side by '2'.
0.5 + -2.5a + a2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -2.5a + -0.5 + a2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -2.5a + a2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -2.5a + a2 = 0 + -0.5
-2.5a + a2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-2.5a + a2 = -0.5

The a term is -2.5a.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5a + 1.5625 + a2 = -0.5 + 1.5625

Reorder the terms:
1.5625 + -2.5a + a2 = -0.5 + 1.5625

Combine like terms: -0.5 + 1.5625 = 1.0625
1.5625 + -2.5a + a2 = 1.0625

Factor a perfect square on the left side:
(a + -1.25)(a + -1.25) = 1.0625
