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

Divide each side by '-5'.
-2 + 0.4t + t2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + 0.4t + 2 + t2 = 0 + 2

Reorder the terms:
-2 + 2 + 0.4t + t2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 0.4t + t2 = 0 + 2
0.4t + t2 = 0 + 2

Combine like terms: 0 + 2 = 2
0.4t + t2 = 2

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 = 2 + 0.04

Reorder the terms:
0.04 + 0.4t + t2 = 2 + 0.04

Combine like terms: 2 + 0.04 = 2.04
0.04 + 0.4t + t2 = 2.04

Factor a perfect square on the left side:
(t + 0.2)(t + 0.2) = 2.04

Calculate the square root of the right side: 1.428285686

Break this problem into two subproblems by setting 
(t + 0.2) equal to 1.428285686 and -1.428285686.

Subproblem 1

t + 0.2 = 1.428285686 Simplifying t + 0.2 = 1.428285686 Reorder the terms: 0.2 + t = 1.428285686 Solving 0.2 + t = 1.428285686 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + t = 1.428285686 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + t = 1.428285686 + -0.2 t = 1.428285686 + -0.2 Combine like terms: 1.428285686 + -0.2 = 1.228285686 t = 1.228285686 Simplifying t = 1.228285686
