Solving for variable 't'.

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

Divide each side by '5'.
-0.4 + 4.8t + t2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + 4.8t + 0.4 + t2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + 4.8t + t2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + 4.8t + t2 = 0 + 0.4
4.8t + t2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
4.8t + t2 = 0.4

The t term is 4.8t.  Take half its coefficient (2.4).
Square it (5.76) and add it to both sides.

Add '5.76' to each side of the equation.
4.8t + 5.76 + t2 = 0.4 + 5.76

Reorder the terms:
5.76 + 4.8t + t2 = 0.4 + 5.76

Combine like terms: 0.4 + 5.76 = 6.16
5.76 + 4.8t + t2 = 6.16

Factor a perfect square on the left side:
(t + 2.4)(t + 2.4) = 6.16
