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

Divide each side by '4'.
-1.25 + -0.75t + t2 = 0

Move the constant term to the right:

Add '1.25' to each side of the equation.
-1.25 + -0.75t + 1.25 + t2 = 0 + 1.25

Reorder the terms:
-1.25 + 1.25 + -0.75t + t2 = 0 + 1.25

Combine like terms: -1.25 + 1.25 = 0.00
0.00 + -0.75t + t2 = 0 + 1.25
-0.75t + t2 = 0 + 1.25

Combine like terms: 0 + 1.25 = 1.25
-0.75t + t2 = 1.25

The t term is -0.75t.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75t + 0.140625 + t2 = 1.25 + 0.140625

Reorder the terms:
0.140625 + -0.75t + t2 = 1.25 + 0.140625

Combine like terms: 1.25 + 0.140625 = 1.390625
0.140625 + -0.75t + t2 = 1.390625

Factor a perfect square on the left side:
(t + -0.375)(t + -0.375) = 1.390625

Calculate the square root of the right side: 1.179247642

Break this problem into two subproblems by setting 
(t + -0.375) equal to 1.179247642 and -1.179247642.

Subproblem 1
t + -0.375 = 1.179247642

Simplifying
t + -0.375 = 1.179247642

Reorder the terms:
-0.375 + t = 1.179247642

Solving
-0.375 + t = 1.179247642

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '0.375' to each side of the equation.
-0.375 + 0.375 + t = 1.179247642 + 0.375

Combine like terms: -0.375 + 0.375 = 0.000
0.000 + t = 1.179247642 + 0.375
t = 1.179247642 + 0.375

Combine like terms: 1.179247642 + 0.375 = 1.554247642
