Solving for variable 't'.

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

Divide each side by '2'.
-11.25 + (7t) + t2 = 0

Move the constant term to the right:

Add '11.25' to each side of the equation.
-11.25 + (7t) + 11.25 + t2 = 0 + 11.25

Reorder the terms:
-11.25 + 11.25 + (7t) + t2 = 0 + 11.25

Combine like terms: -11.25 + 11.25 = 0.00
0.00 + (7t) + t2 = 0 + 11.25
(7t) + t2 = 0 + 11.25

Combine like terms: 0 + 11.25 = 11.25
(7t) + t2 = 11.25

The t term is (7t).  Take half its coefficient (3.5).
Square it (12.25) and add it to both sides.

Add '12.25' to each side of the equation.
(7t) + 12.25 + t2 = 11.25 + 12.25

Reorder the terms:
12.25 + (7t) + t2 = 11.25 + 12.25

Combine like terms: 11.25 + 12.25 = 23.5
12.25 + (7t) + t2 = 23.5
