Divide each side by '12'.
0.5833333333 + -1.5t + t2 = 0

Move the constant term to the right:

Add '-0.5833333333' to each side of the equation.
0.5833333333 + -1.5t + -0.5833333333 + t2 = 0 + -0.5833333333

Reorder the terms:
0.5833333333 + -0.5833333333 + -1.5t + t2 = 0 + -0.5833333333

Combine like terms: 0.5833333333 + -0.5833333333 = 0.0000000000
0.0000000000 + -1.5t + t2 = 0 + -0.5833333333
-1.5t + t2 = 0 + -0.5833333333

Combine like terms: 0 + -0.5833333333 = -0.5833333333
-1.5t + t2 = -0.5833333333

The t term is -1.5t.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5t + 0.5625 + t2 = -0.5833333333 + 0.5625

Reorder the terms:
0.5625 + -1.5t + t2 = -0.5833333333 + 0.5625

Combine like terms: -0.5833333333 + 0.5625 = -0.0208333333
0.5625 + -1.5t + t2 = -0.0208333333

Factor a perfect square on the left side:
(t + -0.75)(t + -0.75) = -0.0208333333

Can't calculate square root of the right side.
