Solving for variable 't'.

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

Divide each side by '4'.
-8.75 + 6t + t2 = 0

Move the constant term to the right:

Add '8.75' to each side of the equation.
-8.75 + 6t + 8.75 + t2 = 0 + 8.75

Reorder the terms:
-8.75 + 8.75 + 6t + t2 = 0 + 8.75

Combine like terms: -8.75 + 8.75 = 0.00
0.00 + 6t + t2 = 0 + 8.75
6t + t2 = 0 + 8.75

Combine like terms: 0 + 8.75 = 8.75
6t + t2 = 8.75

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 = 8.75 + 9

Reorder the terms:
9 + 6t + t2 = 8.75 + 9

Combine like terms: 8.75 + 9 = 17.75
9 + 6t + t2 = 17.75

Factor a perfect square on the left side:
(t + 3)(t + 3) = 17.75
