Divide each side by '64'.
-0.015625 + -0.25t + t2 = 0

Move the constant term to the right:

Add '0.015625' to each side of the equation.
-0.015625 + -0.25t + 0.015625 + t2 = 0 + 0.015625

Reorder the terms:
-0.015625 + 0.015625 + -0.25t + t2 = 0 + 0.015625

Combine like terms: -0.015625 + 0.015625 = 0.000000
0.000000 + -0.25t + t2 = 0 + 0.015625
-0.25t + t2 = 0 + 0.015625

Combine like terms: 0 + 0.015625 = 0.015625
-0.25t + t2 = 0.015625

The t term is -0.25t.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25t + 0.015625 + t2 = 0.015625 + 0.015625

Reorder the terms:
0.015625 + -0.25t + t2 = 0.015625 + 0.015625

Combine like terms: 0.015625 + 0.015625 = 0.03125
0.015625 + -0.25t + t2 = 0.03125
