9 + -2t + t2 = 0

Solving
9 + -2t + t2 = 0

Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '-9' to each side of the equation.
9 + -2t + -9 + t2 = 0 + -9

Reorder the terms:
9 + -9 + -2t + t2 = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -2t + t2 = 0 + -9
-2t + t2 = 0 + -9

Combine like terms: 0 + -9 = -9
-2t + t2 = -9

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 = -9 + 1

Reorder the terms:
1 + -2t + t2 = -9 + 1

Combine like terms: -9 + 1 = -8
1 + -2t + t2 = -8

Factor a perfect square on the left side:
(t + -1)(t + -1) = -8

Can't calculate square root of the right side.
