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

Divide each side by '5'.
-0.2 + -5t + t2 = 0

Move the constant term to the right:

Add '0.2' to each side of the equation.
-0.2 + -5t + 0.2 + t2 = 0 + 0.2

Reorder the terms:
-0.2 + 0.2 + -5t + t2 = 0 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + -5t + t2 = 0 + 0.2
-5t + t2 = 0 + 0.2

Combine like terms: 0 + 0.2 = 0.2
-5t + t2 = 0.2

The t term is -5t.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5t + 6.25 + t2 = 0.2 + 6.25

Reorder the terms:
6.25 + -5t + t2 = 0.2 + 6.25
