Solving for variable 't'.

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

Divide each side by '8'.
-0.375 + 0.75t + t2 = 0

Move the constant term to the right:

Add '0.375' to each side of the equation.
-0.375 + 0.75t + 0.375 + t2 = 0 + 0.375

Reorder the terms:
-0.375 + 0.375 + 0.75t + t2 = 0 + 0.375

Combine like terms: -0.375 + 0.375 = 0.000
0.000 + 0.75t + t2 = 0 + 0.375
0.75t + t2 = 0 + 0.375

Combine like terms: 0 + 0.375 = 0.375
0.75t + t2 = 0.375

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 = 0.375 + 0.140625

Reorder the terms:
0.140625 + 0.75t + t2 = 0.375 + 0.140625

Combine like terms: 0.375 + 0.140625 = 0.515625
0.140625 + 0.75t + t2 = 0.515625
