-1 + -24t + 4t2 = 0

Solving for variable 't'.

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

Divide each side by '4'.
-0.25 + -6t + t2 = 0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + -6t + 0.25 + t2 = 0 + 0.25

Reorder the terms:
-0.25 + 0.25 + -6t + t2 = 0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + -6t + t2 = 0 + 0.25
-6t + t2 = 0 + 0.25

Combine like terms: 0 + 0.25 = 0.25
-6t + t2 = 0.25

The t term is -6t.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6t + 9 + t2 = 0.25 + 9

Reorder the terms:
9 + -6t + t2 = 0.25 + 9

Combine like terms: 0.25 + 9 = 9.25
9 + -6t + t2 = 9.25

Factor a perfect square on the left side:
(t + -3)(t + -3) = 9.25

Calculate the square root of the right side: 3.041381265

Break this problem into two subproblems by setting 
(t + -3) equal to 3.041381265 and -3.041381265.
