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

Divide each side by '-8'.
-8.875 + 2t + t2 = 0

Move the constant term to the right:

Add '8.875' to each side of the equation.
-8.875 + 2t + 8.875 + t2 = 0 + 8.875

Reorder the terms:
-8.875 + 8.875 + 2t + t2 = 0 + 8.875

Combine like terms: -8.875 + 8.875 = 0.000
0.000 + 2t + t2 = 0 + 8.875
2t + t2 = 0 + 8.875

Combine like terms: 0 + 8.875 = 8.875
2t + t2 = 8.875

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 = 8.875 + 1

Reorder the terms:
1 + 2t + t2 = 8.875 + 1

Combine like terms: 8.875 + 1 = 9.875
1 + 2t + t2 = 9.875

Factor a perfect square on the left side:
(t + 1)(t + 1) = 9.875

Calculate the square root of the right side: 3.142451272

Break this problem into two subproblems by setting 
(t + 1) equal to 3.142451272 and -3.142451272.

Subproblem 1
t + 1 = 3.142451272

Simplifying
t + 1 = 3.142451272

Reorder the terms:
1 + t = 3.142451272

Solving
1 + t = 3.142451272

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 = 3.142451272 + -1

Combine like terms: 1 + -1 = 0
0 + t = 3.142451272 + -1
t = 3.142451272 + -1

Combine like terms: 3.142451272 + -1 = 2.142451272
t = 2.142451272

Simplifying
t = 2.142451272

Subproblem 2
t + 1 = -3.142451272

Simplifying
t + 1 = -3.142451272

Reorder the terms:
1 + t = -3.142451272

Solving
1 + t = -3.142451272

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 = -3.142451272 + -1

Combine like terms: 1 + -1 = 0
0 + t = -3.142451272 + -1
t = -3.142451272 + -1

Combine like terms: -3.142451272 + -1 = -4.142451272
t = -4.142451272

Simplifying
t = -4.142451272
