Begin completing the square.

Move the constant term to the right:

Add '220' to each side of the equation.
-220 + -1t + 220 + t2 = 0 + 220

Reorder the terms:
-220 + 220 + -1t + t2 = 0 + 220

Combine like terms: -220 + 220 = 0
0 + -1t + t2 = 0 + 220
-1t + t2 = 0 + 220

Combine like terms: 0 + 220 = 220
-1t + t2 = 220

The t term is -1t.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1t + 0.25 + t2 = 220 + 0.25

Reorder the terms:
0.25 + -1t + t2 = 220 + 0.25

Combine like terms: 220 + 0.25 = 220.25
0.25 + -1t + t2 = 220.25

Factor a perfect square on the left side:
(t + -0.5)(t + -0.5) = 220.25
