Solving for variable 't'.

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

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

Move the constant term to the right:

Add '16' to each side of the equation.
-16 + 0.0625t + 16 + t2 = 0 + 16

Reorder the terms:
-16 + 16 + 0.0625t + t2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + 0.0625t + t2 = 0 + 16
0.0625t + t2 = 0 + 16

Combine like terms: 0 + 16 = 16
0.0625t + t2 = 16

The t term is t.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.0625t + 0.25 + t2 = 16 + 0.25

Reorder the terms:
0.25 + 0.0625t + t2 = 16 + 0.25

Combine like terms: 16 + 0.25 = 16.25
0.25 + 0.0625t + t2 = 16.25

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = 16.25

Calculate the square root of the right side: 4.031128874
