-6 + -2t + t2 = 0

Solving
-6 + -2t + t2 = 0

Begin completing the square.

Move the constant term to the right:

Add '6' to each side of the equation.
-6 + -2t + 6 + t2 = 0 + 6

Reorder the terms:
-6 + 6 + -2t + t2 = 0 + 6

Combine like terms: -6 + 6 = 0
0 + -2t + t2 = 0 + 6
-2t + t2 = 0 + 6

Combine like terms: 0 + 6 = 6
-2t + t2 = 6

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 = 6 + 1

Reorder the terms:
1 + -2t + t2 = 6 + 1

Combine like terms: 6 + 1 = 7
1 + -2t + t2 = 7

Factor a perfect square on the left side:
(t + -1)(t + -1) = 7
