Solving for variable 't'.

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

Divide each side by '4'.
3.25 + 6t + t2 = 0

Move the constant term to the right:

Add '-3.25' to each side of the equation.
3.25 + 6t + -3.25 + t2 = 0 + -3.25

Reorder the terms:
3.25 + -3.25 + 6t + t2 = 0 + -3.25

Combine like terms: 3.25 + -3.25 = 0.00
0.00 + 6t + t2 = 0 + -3.25
6t + t2 = 0 + -3.25

Combine like terms: 0 + -3.25 = -3.25
6t + t2 = -3.25

The t term is 6t.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6t + 9 + t2 = -3.25 + 9

Reorder the terms:
9 + 6t + t2 = -3.25 + 9

Combine like terms: -3.25 + 9 = 5.75
9 + 6t + t2 = 5.75

Factor a perfect square on the left side:
(t + 3)(t + 3) = 5.75

Calculate the square root of the right side: 2.397915762
