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

Divide each side by '5'.
-0.4 + -4t + t2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + -4t + 0.4 + t2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + -4t + t2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + -4t + t2 = 0 + 0.4
-4t + t2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
-4t + t2 = 0.4

The t term is -4t.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4t + 4 + t2 = 0.4 + 4

Reorder the terms:
4 + -4t + t2 = 0.4 + 4

Combine like terms: 0.4 + 4 = 4.4
4 + -4t + t2 = 4.4

Factor a perfect square on the left side:
(t + -2)(t + -2) = 4.4
