-5 the coefficient of the squared term: 

Divide each side by '-5'.
12 + 1.026t + t2 = 0

Move the constant term to the right:

Add '-12' to each side of the equation.
12 + 1.026t + -12 + t2 = 0 + -12

Reorder the terms:
12 + -12 + 1.026t + t2 = 0 + -12

Combine like terms: 12 + -12 = 0
0 + 1.026t + t2 = 0 + -12
1.026t + t2 = 0 + -12

Combine like terms: 0 + -12 = -12
1.026t + t2 = -12

The t term is 1.026t.  Take half its coefficient (0.513).
