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

Divide each side by '16'.
-0.0625 + -0.5t + t2 = 0

Move the constant term to the right:

Add '0.0625' to each side of the equation.
-0.0625 + -0.5t + 0.0625 + t2 = 0 + 0.0625

Reorder the terms:
-0.0625 + 0.0625 + -0.5t + t2 = 0 + 0.0625

Combine like terms: -0.0625 + 0.0625 = 0.0000
0.0000 + -0.5t + t2 = 0 + 0.0625
-0.5t + t2 = 0 + 0.0625

Combine like terms: 0 + 0.0625 = 0.0625
-0.5t + t2 = 0.0625

The t term is -0.5t.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5t + 0.0625 + t2 = 0.0625 + 0.0625

Reorder the terms:
0.0625 + -0.5t + t2 = 0.0625 + 0.0625

Combine like terms: 0.0625 + 0.0625 = 0.125
0.0625 + -0.5t + t2 = 0.125

Factor a perfect square on the left side:
(t + -0.25)(t + -0.25) = 0.125

Calculate the square root of the right side: 0.353553391
