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

Divide each side by '-16'.
-0.3125 + 1.625t + t2 = 0

Move the constant term to the right:

Add '0.3125' to each side of the equation.
-0.3125 + 1.625t + 0.3125 + t2 = 0 + 0.3125

Reorder the terms:
-0.3125 + 0.3125 + 1.625t + t2 = 0 + 0.3125

Combine like terms: -0.3125 + 0.3125 = 0.0000
0.0000 + 1.625t + t2 = 0 + 0.3125
1.625t + t2 = 0 + 0.3125

Combine like terms: 0 + 0.3125 = 0.3125
1.625t + t2 = 0.3125

The t term is 1.625t.  Take half its coefficient (0.8125).
