1 = 12t + 0.5t2

Solving
1 = 12t + 0.5t2

Solving for variable 't'.

Reorder the terms:
1 + -12t + -0.5t2 = 12t + -12t + 0.5t2 + -0.5t2

Combine like terms: 12t + -12t = 0
1 + -12t + -0.5t2 = 0 + 0.5t2 + -0.5t2
1 + -12t + -0.5t2 = 0.5t2 + -0.5t2

Combine like terms: 0.5t2 + -0.5t2 = 0.0
1 + -12t + -0.5t2 = 0.0

Begin completing the square.  Divide all terms by
-0.5 the coefficient of the squared term: 

Divide each side by '-0.5'.
-2 + 24t + t2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + 24t + 2 + t2 = 0 + 2

Reorder the terms:
-2 + 2 + 24t + t2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 24t + t2 = 0 + 2
24t + t2 = 0 + 2

Combine like terms: 0 + 2 = 2
24t + t2 = 2

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 = 2 + 144

Reorder the terms:
144 + 24t + t2 = 2 + 144

Combine like terms: 2 + 144 = 146
144 + 24t + t2 = 146

Factor a perfect square on the left side:
(t + 12)(t + 12) = 146
