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

Divide each side by '0.01'.
-3740 + 70t + t2 = 0

Move the constant term to the right:

Add '3740' to each side of the equation.
-3740 + 70t + 3740 + t2 = 0 + 3740

Reorder the terms:
-3740 + 3740 + 70t + t2 = 0 + 3740

Combine like terms: -3740 + 3740 = 0
0 + 70t + t2 = 0 + 3740
70t + t2 = 0 + 3740

Combine like terms: 0 + 3740 = 3740
70t + t2 = 3740

The t term is 70t.  Take half its coefficient (35).
Square it (1225) and add it to both sides.

Add '1225' to each side of the equation.
70t + 1225 + t2 = 3740 + 1225
