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

Divide each side by '4'.
-4.25 + 3t + t2 = 0

Move the constant term to the right:

Add '4.25' to each side of the equation.
-4.25 + 3t + 4.25 + t2 = 0 + 4.25

Reorder the terms:
-4.25 + 4.25 + 3t + t2 = 0 + 4.25

Combine like terms: -4.25 + 4.25 = 0.00
0.00 + 3t + t2 = 0 + 4.25
3t + t2 = 0 + 4.25

Combine like terms: 0 + 4.25 = 4.25
3t + t2 = 4.25

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 = 4.25 + 2.25

Reorder the terms:
2.25 + 3t + t2 = 4.25 + 2.25

Combine like terms: 4.25 + 2.25 = 6.5
2.25 + 3t + t2 = 6.5
