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

Divide each side by '16'.
0.625 + -1.6875t + t2 = 0

Move the constant term to the right:

Add '-0.625' to each side of the equation.
0.625 + -1.6875t + -0.625 + t2 = 0 + -0.625

Reorder the terms:
0.625 + -0.625 + -1.6875t + t2 = 0 + -0.625

Combine like terms: 0.625 + -0.625 = 0.000
0.000 + -1.6875t + t2 = 0 + -0.625
-1.6875t + t2 = 0 + -0.625

Combine like terms: 0 + -0.625 = -0.625
-1.6875t + t2 = -0.625

The t term is -1.6875t.  Take half its coefficient (-0.84375).
Square it (0.7119140625) and add it to both sides.

Add '0.7119140625' to each side of the equation.
-1.6875t + 0.7119140625 + t2 = -0.625 + 0.7119140625

Reorder the terms:
0.7119140625 + -1.6875t + t2 = -0.625 + 0.7119140625

Combine like terms: -0.625 + 0.7119140625 = 0.0869140625
0.7119140625 + -1.6875t + t2 = 0.0869140625

Factor a perfect square on the left side:
(t + -0.84375)(t + -0.84375) = 0.0869140625

Calculate the square root of the right side: 0.29481191
