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 + 0.4t + t2 = 0

Move the constant term to the right:

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

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

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

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

The t term is 0.4t.  Take half its coefficient (0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
0.4t + 0.04 + t2 = -0.4 + 0.04

Reorder the terms:
0.04 + 0.4t + t2 = -0.4 + 0.04

Combine like terms: -0.4 + 0.04 = -0.36
0.04 + 0.4t + t2 = -0.36

Factor a perfect square on the left side:
(t + 0.2)(t + 0.2) = -0.36

Can't calculate square root of the right side.

The solution to this equation could not be determined.
