Subproblem 1
Set the factor '(-10 + 2t + t2)' equal to zero and attempt to solve:

Simplifying
-10 + 2t + t2 = 0

Solving
-10 + 2t + t2 = 0

Begin completing the square.

Move the constant term to the right:

Add '10' to each side of the equation.
-10 + 2t + 10 + t2 = 0 + 10

Reorder the terms:
-10 + 10 + 2t + t2 = 0 + 10

Combine like terms: -10 + 10 = 0
0 + 2t + t2 = 0 + 10
2t + t2 = 0 + 10

Combine like terms: 0 + 10 = 10
2t + t2 = 10

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 = 10 + 1

Reorder the terms:
1 + 2t + t2 = 10 + 1

Combine like terms: 10 + 1 = 11
1 + 2t + t2 = 11

Factor a perfect square on the left side:
(t + 1)(t + 1) = 11

Calculate the square root of the right side: 3.31662479

Break this problem into two subproblems by setting 
(t + 1) equal to 3.31662479 and -3.31662479.

Subproblem 1
t + 1 = 3.31662479

Simplifying
t + 1 = 3.31662479

Reorder the terms:
1 + t = 3.31662479

Solving
1 + t = 3.31662479

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 = 3.31662479 + -1

Combine like terms: 1 + -1 = 0
0 + t = 3.31662479 + -1
t = 3.31662479 + -1

Combine like terms: 3.31662479 + -1 = 2.31662479
t = 2.31662479

Simplifying
t = 2.31662479

Subproblem 2
t + 1 = -3.31662479

Simplifying
t + 1 = -3.31662479

Reorder the terms:
1 + t = -3.31662479

Solving
1 + t = -3.31662479

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 = -3.31662479 + -1

Combine like terms: 1 + -1 = 0
0 + t = -3.31662479 + -1
t = -3.31662479 + -1

Combine like terms: -3.31662479 + -1 = -4.31662479
t = -4.31662479

Simplifying
t = -4.31662479

Solution
The solution to the problem is based on the solutions
from the subproblems.
t = {2.31662479, -4.31662479}
Solution
t = {2.31662479, -4.31662479}
