Solving for variable 't'.

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 = -5
1 + 2t + t2 = -5

Factor a perfect square on the left side:
(t + 1)(t + 1) = -5

Can't calculate square root of the right side.
