Begin completing the square.  Divide all terms by
-8 the coefficient of the squared term: 

Divide each side by '-8'.
-7.875 + 2t + t2 = 0

Move the constant term to the right:

Add '7.875' to each side of the equation.
-7.875 + 2t + 7.875 + t2 = 0 + 7.875

Reorder the terms:
-7.875 + 7.875 + 2t + t2 = 0 + 7.875

Combine like terms: -7.875 + 7.875 = 0.000
0.000 + 2t + t2 = 0 + 7.875
2t + t2 = 0 + 7.875

Combine like terms: 0 + 7.875 = 7.875
2t + t2 = 7.875

The t term is 2t.  Take half its coefficient (1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
2t + 1 + t2 = 7.875 + 1

Reorder the terms:
1 + 2t + t2 = 7.875 + 1

Combine like terms: 7.875 + 1 = 8.875
1 + 2t + t2 = 8.875

Factor a perfect square on the left side:
(t + 1)(t + 1) = 8.875

Calculate the square root of the right side: 2.979093822

Break this problem into two subproblems by setting 
(t + 1) equal to 2.979093822 and -2.979093822.

Subproblem 1
t + 1 = 2.979093822

Simplifying
t + 1 = 2.979093822

Reorder the terms:
1 + t = 2.979093822

Solving
1 + t = 2.979093822

Solving for variable 't'.

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

Add '-1' to each side of the equation.
1 + -1 + t = 2.979093822 + -1

Combine like terms: 1 + -1 = 0
0 + t = 2.979093822 + -1
t = 2.979093822 + -1

Combine like terms: 2.979093822 + -1 = 1.979093822
t = 1.979093822

Simplifying
t = 1.979093822

Subproblem 2
t + 1 = -2.979093822

Simplifying
t + 1 = -2.979093822

Reorder the terms:
1 + t = -2.979093822

Solving
1 + t = -2.979093822

Solving for variable 't'.

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

Add '-1' to each side of the equation.
1 + -1 + t = -2.979093822 + -1

Combine like terms: 1 + -1 = 0
0 + t = -2.979093822 + -1
t = -2.979093822 + -1

Combine like terms: -2.979093822 + -1 = -3.979093822
t = -3.979093822

Simplifying
t = -3.979093822

Solution
The solution to the problem is based on the solutions
from the subproblems.
t = {1.979093822, -3.979093822}
