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

Divide each side by '-16'.
-0.25 + 1.0625t + t2 = 0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + 1.0625t + 0.25 + t2 = 0 + 0.25

Reorder the terms:
-0.25 + 0.25 + 1.0625t + t2 = 0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + 1.0625t + t2 = 0 + 0.25
1.0625t + t2 = 0 + 0.25

Combine like terms: 0 + 0.25 = 0.25
1.0625t + t2 = 0.25

The t term is 1.0625t.  Take half its coefficient (0.53125).
Square it (0.2822265625) and add it to both sides.

Add '0.2822265625' to each side of the equation.
1.0625t + 0.2822265625 + t2 = 0.25 + 0.2822265625

Reorder the terms:
0.2822265625 + 1.0625t + t2 = 0.25 + 0.2822265625

Combine like terms: 0.25 + 0.2822265625 = 0.5322265625
