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

Divide each side by '16'.
18.3125 + -1.25t + t2 = 0

Move the constant term to the right:

Add '-18.3125' to each side of the equation.
18.3125 + -1.25t + -18.3125 + t2 = 0 + -18.3125

Reorder the terms:
18.3125 + -18.3125 + -1.25t + t2 = 0 + -18.3125

Combine like terms: 18.3125 + -18.3125 = 0.0000
0.0000 + -1.25t + t2 = 0 + -18.3125
-1.25t + t2 = 0 + -18.3125

Combine like terms: 0 + -18.3125 = -18.3125
-1.25t + t2 = -18.3125

The t term is -1.25t.  Take half its coefficient (-0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
-1.25t + 0.390625 + t2 = -18.3125 + 0.390625

Reorder the terms:
0.390625 + -1.25t + t2 = -18.3125 + 0.390625

Combine like terms: -18.3125 + 0.390625 = -17.921875
0.390625 + -1.25t + t2 = -17.921875

Factor a perfect square on the left side:
(t + -0.625)(t + -0.625) = -17.921875

Can't calculate square root of the right side.
