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

Divide each side by '-16'.
-0.0625 + -1.5t + t2 = 0

Move the constant term to the right:

Add '0.0625' to each side of the equation.
-0.0625 + -1.5t + 0.0625 + t2 = 0 + 0.0625

Reorder the terms:
-0.0625 + 0.0625 + -1.5t + t2 = 0 + 0.0625

Combine like terms: -0.0625 + 0.0625 = 0.0000
0.0000 + -1.5t + t2 = 0 + 0.0625
-1.5t + t2 = 0 + 0.0625

Combine like terms: 0 + 0.0625 = 0.0625
-1.5t + t2 = 0.0625

The t term is -1.5t.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5t + 0.5625 + t2 = 0.0625 + 0.5625

Reorder the terms:
0.5625 + -1.5t + t2 = 0.0625 + 0.5625

Combine like terms: 0.0625 + 0.5625 = 0.625
0.5625 + -1.5t + t2 = 0.625

Factor a perfect square on the left side:
(t + -0.75)(t + -0.75) = 0.625

Calculate the square root of the right side: 0.790569415
