Begin completing the square.  Divide all terms by
0.0625 the coefficient of the squared term: 

Divide each side by '0.0625'.
160 + -32t + t2 = 0

Move the constant term to the right:

Add '-160' to each side of the equation.
160 + -32t + -160 + t2 = 0 + -160

Reorder the terms:
160 + -160 + -32t + t2 = 0 + -160

Combine like terms: 160 + -160 = 0
0 + -32t + t2 = 0 + -160
-32t + t2 = 0 + -160

Combine like terms: 0 + -160 = -160
-32t + t2 = -160

The t term is -32t.  Take half its coefficient (-16).
Square it (256) and add it to both sides.
