Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '-72' to each side of the equation.
72 + 6t + -72 + t2 = 0 + -72

Reorder the terms:
72 + -72 + 6t + t2 = 0 + -72

Combine like terms: 72 + -72 = 0
0 + 6t + t2 = 0 + -72
6t + t2 = 0 + -72

Combine like terms: 0 + -72 = -72
6t + t2 = -72

The t term is 6t.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6t + 9 + t2 = -72 + 9

Reorder the terms:
9 + 6t + t2 = -72 + 9

Combine like terms: -72 + 9 = -63
9 + 6t + t2 = -63

Factor a perfect square on the left side:
(t + 3)(t + 3) = -63

Can't calculate square root of the right side.
