Solving for variable 't'.

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

Divide each side by '2'.
-9.5 + -3t + t2 = 0

Move the constant term to the right:

Add '9.5' to each side of the equation.
-9.5 + -3t + 9.5 + t2 = 0 + 9.5

Reorder the terms:
-9.5 + 9.5 + -3t + t2 = 0 + 9.5

Combine like terms: -9.5 + 9.5 = 0.0
0.0 + -3t + t2 = 0 + 9.5
-3t + t2 = 0 + 9.5

Combine like terms: 0 + 9.5 = 9.5
-3t + t2 = 9.5

The t term is -3t.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3t + 2.25 + t2 = 9.5 + 2.25

Reorder the terms:
2.25 + -3t + t2 = 9.5 + 2.25

Combine like terms: 9.5 + 2.25 = 11.75
2.25 + -3t + t2 = 11.75

Factor a perfect square on the left side:
(t + -1.5)(t + -1.5) = 11.75
