Begin completing the square.  Divide all terms by
-0.25 the coefficient of the squared term: 

Divide each side by '-0.25'.
-20 + -24t + t2 = 0

Move the constant term to the right:

Add '20' to each side of the equation.
-20 + -24t + 20 + t2 = 0 + 20

Reorder the terms:
-20 + 20 + -24t + t2 = 0 + 20

Combine like terms: -20 + 20 = 0
0 + -24t + t2 = 0 + 20
-24t + t2 = 0 + 20

Combine like terms: 0 + 20 = 20
-24t + t2 = 20

The t term is -24t.  Take half its coefficient (-12).
Square it (144) and add it to both sides.

Add '144' to each side of the equation.
-24t + 144 + t2 = 20 + 144

Reorder the terms:
144 + -24t + t2 = 20 + 144

Combine like terms: 20 + 144 = 164
144 + -24t + t2 = 164

Factor a perfect square on the left side:
(t + -12)(t + -12) = 164

Calculate the square root of the right side: 12.806248475
