Begin completing the square.  Divide all terms by
-7 the coefficient of the squared term: 

Divide each side by '-7'.
-1.02 + 5t + t2 = 0

Move the constant term to the right:

Add '1.02' to each side of the equation.
-1.02 + 5t + 1.02 + t2 = 0 + 1.02

Reorder the terms:
-1.02 + 1.02 + 5t + t2 = 0 + 1.02

Combine like terms: -1.02 + 1.02 = 0.00
0.00 + 5t + t2 = 0 + 1.02
5t + t2 = 0 + 1.02

Combine like terms: 0 + 1.02 = 1.02
5t + t2 = 1.02

The t term is 5t.  Take half its coefficient (2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
5t + 6.25 + t2 = 1.02 + 6.25

Reorder the terms:
6.25 + 5t + t2 = 1.02 + 6.25

Combine like terms: 1.02 + 6.25 = 7.27
6.25 + 5t + t2 = 7.27
