5 the coefficient of the squared term: 

Divide each side by '5'.
-12 + -1.4t + t2 = 0

Move the constant term to the right:

Add '12' to each side of the equation.
-12 + -1.4t + 12 + t2 = 0 + 12

Reorder the terms:
-12 + 12 + -1.4t + t2 = 0 + 12

Combine like terms: -12 + 12 = 0
0 + -1.4t + t2 = 0 + 12
-1.4t + t2 = 0 + 12

Combine like terms: 0 + 12 = 12
-1.4t + t2 = 12

The t term is -1.4t.  Take half its coefficient (-0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
-1.4t + 0.49 + t2 = 12 + 0.49

Reorder the terms:
0.49 + -1.4t + t2 = 12 + 0.49

Combine like terms: 12 + 0.49 = 12.49
0.49 + -1.4t + t2 = 12.49
