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

Divide each side by '5'.
-4.6 + 0.8x + x2 = 0

Move the constant term to the right:

Add '4.6' to each side of the equation.
-4.6 + 0.8x + 4.6 + x2 = 0 + 4.6

Reorder the terms:
-4.6 + 4.6 + 0.8x + x2 = 0 + 4.6

Combine like terms: -4.6 + 4.6 = 0.0
0.0 + 0.8x + x2 = 0 + 4.6
0.8x + x2 = 0 + 4.6

Combine like terms: 0 + 4.6 = 4.6
0.8x + x2 = 4.6

The x term is 0.8x.  Take half its coefficient (0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
0.8x + 0.16 + x2 = 4.6 + 0.16

Reorder the terms:
0.16 + 0.8x + x2 = 4.6 + 0.16

Combine like terms: 4.6 + 0.16 = 4.76
0.16 + 0.8x + x2 = 4.76

Factor a perfect square on the left side:
(x + 0.4)(x + 0.4) = 4.76
