22 + -11t + t2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-22' to each side of the equation.
22 + -11t + -22 + t2 = 0 + -22

Reorder the terms:
22 + -22 + -11t + t2 = 0 + -22

Combine like terms: 22 + -22 = 0
0 + -11t + t2 = 0 + -22
-11t + t2 = 0 + -22

Combine like terms: 0 + -22 = -22
-11t + t2 = -22

The t term is -11t.  Take half its coefficient (-5.5).
Square it (30.25) and add it to both sides.

Add '30.25' to each side of the equation.
-11t + 30.25 + t2 = -22 + 30.25

Reorder the terms:
30.25 + -11t + t2 = -22 + 30.25

Combine like terms: -22 + 30.25 = 8.25
30.25 + -11t + t2 = 8.25

Factor a perfect square on the left side:
(t + -5.5)(t + -5.5) = 8.25
