Begin completing the square.  Divide all terms by
-0.05 the coefficient of the squared term: 

Divide each side by '-0.05'.
-480 + 20i + i2 = 0

Move the constant term to the right:

Add '480' to each side of the equation.
-480 + 20i + 480 + i2 = 0 + 480

Reorder the terms:
-480 + 480 + 20i + i2 = 0 + 480

Combine like terms: -480 + 480 = 0
0 + 20i + i2 = 0 + 480
20i + i2 = 0 + 480

Combine like terms: 0 + 480 = 480
20i + i2 = 480

The i term is 20i.  Take half its coefficient (10).
Square it (100) and add it to both sides.

Add '100' to each side of the equation.
20i + 100 + i2 = 480 + 100
