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

Divide each side by '16'.
-1.03125 + -0.5t + t2 = 0

Move the constant term to the right:

Add '1.03125' to each side of the equation.
-1.03125 + -0.5t + 1.03125 + t2 = 0 + 1.03125

Reorder the terms:
-1.03125 + 1.03125 + -0.5t + t2 = 0 + 1.03125

Combine like terms: -1.03125 + 1.03125 = 0.00000
0.00000 + -0.5t + t2 = 0 + 1.03125
-0.5t + t2 = 0 + 1.03125

Combine like terms: 0 + 1.03125 = 1.03125
-0.5t + t2 = 1.03125

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 = 1.03125 + 0.0625

Reorder the terms:
0.0625 + -0.5t + t2 = 1.03125 + 0.0625

Combine like terms: 1.03125 + 0.0625 = 1.09375
0.0625 + -0.5t + t2 = 1.09375
