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

Divide each side by '5'.
-1 + 1.2t + t2 = 0

Move the constant term to the right:

Add '1' to each side of the equation.
-1 + 1.2t + 1 + t2 = 0 + 1

Reorder the terms:
-1 + 1 + 1.2t + t2 = 0 + 1

Combine like terms: -1 + 1 = 0
0 + 1.2t + t2 = 0 + 1
1.2t + t2 = 0 + 1

Combine like terms: 0 + 1 = 1
1.2t + t2 = 1

The t term is 1.2t.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2t + 0.36 + t2 = 1 + 0.36

Reorder the terms:
0.36 + 1.2t + t2 = 1 + 0.36

Combine like terms: 1 + 0.36 = 1.36
0.36 + 1.2t + t2 = 1.36

Factor a perfect square on the left side:
(t + 0.6)(t + 0.6) = 1.36

Calculate the square root of the right side: 1.166190379

Break this problem into two subproblems by setting 
(t + 0.6) equal to 1.166190379 and -1.166190379.

Subproblem 1

t + 0.6 = 1.166190379 Simplifying t + 0.6 = 1.166190379 Reorder the terms: 0.6 + t = 1.166190379 Solving 0.6 + t = 1.166190379 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + t = 1.166190379 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + t = 1.166190379 + -0.6 t = 1.166190379 + -0.6 Combine like terms: 1.166190379 + -0.6 = 0.566190379 t = 0.566190379 Simplifying t = 0.566190379

Subproblem 2

t + 0.6 = -1.166190379 Simplifying t + 0.6 = -1.166190379 Reorder the terms: 0.6 + t = -1.166190379 Solving 0.6 + t = -1.166190379 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.6' to each side of the equation. 0.6 + -0.6 + t = -1.166190379 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + t = -1.166190379 + -0.6 t = -1.166190379 + -0.6 Combine like terms: -1.166190379 + -0.6 = -1.766190379 t = -1.766190379 Simplifying t = -1.766190379

Solution
