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

Divide each side by '2'.
0.5 + -2t + t2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -2t + -0.5 + t2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -2t + t2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -2t + t2 = 0 + -0.5
-2t + t2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-2t + t2 = -0.5

The t term is -2t.  Take half its coefficient (-1).
