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

Divide each side by '-4'.
-10 + 0.75t + t2 = 0

Move the constant term to the right:

Add '10' to each side of the equation.
-10 + 0.75t + 10 + t2 = 0 + 10

Reorder the terms:
-10 + 10 + 0.75t + t2 = 0 + 10

Combine like terms: -10 + 10 = 0
0 + 0.75t + t2 = 0 + 10
0.75t + t2 = 0 + 10

Combine like terms: 0 + 10 = 10
0.75t + t2 = 10

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 = 10 + 0.140625

Reorder the terms:
0.140625 + 0.75t + t2 = 10 + 0.140625

Combine like terms: 10 + 0.140625 = 10.140625
0.140625 + 0.75t + t2 = 10.140625

Factor a perfect square on the left side:
(t + 0.375)(t + 0.375) = 10.140625

Simplifying
t + 0.375 = -3.184434801

Reorder the terms:
0.375 + t = -3.184434801

Solving
0.375 + t = -3.184434801

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 = -3.184434801 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + t = -3.184434801 + -0.375
t = -3.184434801 + -0.375
