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

Divide each side by '16'.
0.3125 + -2t + t2 = 0

Move the constant term to the right:

Add '-0.3125' to each side of the equation.
0.3125 + -2t + -0.3125 + t2 = 0 + -0.3125

Reorder the terms:
0.3125 + -0.3125 + -2t + t2 = 0 + -0.3125

Combine like terms: 0.3125 + -0.3125 = 0.0000
0.0000 + -2t + t2 = 0 + -0.3125
-2t + t2 = 0 + -0.3125

Combine like terms: 0 + -0.3125 = -0.3125
-2t + t2 = -0.3125

The t term is -2t.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2t + 1 + t2 = -0.3125 + 1

Reorder the terms:
1 + -2t + t2 = -0.3125 + 1

Combine like terms: -0.3125 + 1 = 0.6875
1 + -2t + t2 = 0.6875

Factor a perfect square on the left side:
(t + -1)(t + -1) = 0.6875

Calculate the square root of the right side: 0.829156198
