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

Divide each side by '-16'.
-0.1875 + -0.75t + t2 = 0

Move the constant term to the right:

Add '0.1875' to each side of the equation.
-0.1875 + -0.75t + 0.1875 + t2 = 0 + 0.1875

Reorder the terms:
-0.1875 + 0.1875 + -0.75t + t2 = 0 + 0.1875

Combine like terms: -0.1875 + 0.1875 = 0.0000
0.0000 + -0.75t + t2 = 0 + 0.1875
-0.75t + t2 = 0 + 0.1875

Combine like terms: 0 + 0.1875 = 0.1875
-0.75t + t2 = 0.1875

The t term is -0.75t.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75t + 0.140625 + t2 = 0.1875 + 0.140625

Reorder the terms:
0.140625 + -0.75t + t2 = 0.1875 + 0.140625

Combine like terms: 0.1875 + 0.140625 = 0.328125
0.140625 + -0.75t + t2 = 0.328125
