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

Divide each side by '16'.
-0.35 + -0.75t + t2 = 0

Move the constant term to the right:

Add '0.35' to each side of the equation.
-0.35 + -0.75t + 0.35 + t2 = 0 + 0.35

Reorder the terms:
-0.35 + 0.35 + -0.75t + t2 = 0 + 0.35

Combine like terms: -0.35 + 0.35 = 0.00
0.00 + -0.75t + t2 = 0 + 0.35
-0.75t + t2 = 0 + 0.35

Combine like terms: 0 + 0.35 = 0.35
-0.75t + t2 = 0.35

The t term is -0.75t.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75t + 0.140625 + t2 = 0.35 + 0.140625

Reorder the terms:
0.140625 + -0.75t + t2 = 0.35 + 0.140625

Combine like terms: 0.35 + 0.140625 = 0.490625
0.140625 + -0.75t + t2 = 0.490625
