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

Divide each side by '16'.
1.09375 + -2t + t2 = 0

Move the constant term to the right:

Add '-1.09375' to each side of the equation.
1.09375 + -2t + -1.09375 + t2 = 0 + -1.09375

Reorder the terms:
1.09375 + -1.09375 + -2t + t2 = 0 + -1.09375

Combine like terms: 1.09375 + -1.09375 = 0.00000
0.00000 + -2t + t2 = 0 + -1.09375
-2t + t2 = 0 + -1.09375

Combine like terms: 0 + -1.09375 = -1.09375
-2t + t2 = -1.09375

The t term is -2t.  Take half its coefficient (-1).
