Add '0.119' to each side of the equation.
-0.119 + t + 0.119 + t2 = 0 + 0.119

Reorder the terms:
-0.119 + 0.119 + t + t2 = 0 + 0.119

Combine like terms: -0.119 + 0.119 = 0.000
0.000 + t + t2 = 0 + 0.119
t + t2 = 0 + 0.119

Combine like terms: 0 + 0.119 = 0.119
t + t2 = 0.119

The t term is t.  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.
 + 0.25 + t2 = 0.119 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + t2 = 0.119 + 0.25

Combine like terms: 0.119 + 0.25 = 0.369
1.25 + t2 = 0.369

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = 0.369
