Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -8t + -6 + t2 = 0 + -6

Reorder the terms:
6 + -6 + -8t + t2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -8t + t2 = 0 + -6
-8t + t2 = 0 + -6

Combine like terms: 0 + -6 = -6
-8t + t2 = -6

The t term is -8t.  Take half its coefficient (-4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
-8t + 16 + t2 = -6 + 16

Break this problem into two subproblems by setting 
(t + -4) equal to 3.16227766 and -3.16227766.

Subproblem 1
t + -4 = 3.16227766

Simplifying
t + -4 = 3.16227766

Reorder the terms:
-4 + t = 3.16227766

Solving
-4 + t = 3.16227766

Solving for variable 't'.

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

Add '4' to each side of the equation.
-4 + 4 + t = 3.16227766 + 4

Combine like terms: -4 + 4 = 0
0 + t = 3.16227766 + 4
t = 3.16227766 + 4

Combine like terms: 3.16227766 + 4 = 7.16227766
t = 7.16227766

Simplifying
t = 7.16227766

Subproblem 2
t + -4 = -3.16227766

Simplifying
t + -4 = -3.16227766

Reorder the terms:
-4 + t = -3.16227766

Solving
-4 + t = -3.16227766

Solving for variable 't'.

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

Add '4' to each side of the equation.
-4 + 4 + t = -3.16227766 + 4

Combine like terms: -4 + 4 = 0
0 + t = -3.16227766 + 4
t = -3.16227766 + 4

Combine like terms: -3.16227766 + 4 = 0.83772234
t = 0.83772234

Simplifying
t = 0.83772234

Solution
