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

Divide each side by '16'.
-0.1875 + -2t + t2 = 0

Move the constant term to the right:

Add '0.1875' to each side of the equation.
-0.1875 + -2t + 0.1875 + t2 = 0 + 0.1875

Reorder the terms:
-0.1875 + 0.1875 + -2t + t2 = 0 + 0.1875

Combine like terms: -0.1875 + 0.1875 = 0.0000
0.0000 + -2t + t2 = 0 + 0.1875
-2t + t2 = 0 + 0.1875

Combine like terms: 0 + 0.1875 = 0.1875
-2t + t2 = 0.1875

The t term is -2t.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2t + 1 + t2 = 0.1875 + 1

Reorder the terms:
1 + -2t + t2 = 0.1875 + 1

Combine like terms: 0.1875 + 1 = 1.1875
1 + -2t + t2 = 1.1875

Factor a perfect square on the left side:
(t + -1)(t + -1) = 1.1875
