Solving for variable 't'.

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

Divide each side by '8'.
0.625 + 1.125t + t2 = 0

Move the constant term to the right:

Add '-0.625' to each side of the equation.
0.625 + 1.125t + -0.625 + t2 = 0 + -0.625

Reorder the terms:
0.625 + -0.625 + 1.125t + t2 = 0 + -0.625

Combine like terms: 0.625 + -0.625 = 0.000
0.000 + 1.125t + t2 = 0 + -0.625
1.125t + t2 = 0 + -0.625

Combine like terms: 0 + -0.625 = -0.625
1.125t + t2 = -0.625

The t term is 1.125t.  Take half its coefficient (0.5625).
Square it (0.31640625) and add it to both sides.
