-1 + -8t + 10t2 = 0

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

Divide each side by '10'.
-0.1 + -0.8t + t2 = 0

Move the constant term to the right:

Add '0.1' to each side of the equation.
-0.1 + -0.8t + 0.1 + t2 = 0 + 0.1

Reorder the terms:
-0.1 + 0.1 + -0.8t + t2 = 0 + 0.1

Combine like terms: -0.1 + 0.1 = 0.0
0.0 + -0.8t + t2 = 0 + 0.1
-0.8t + t2 = 0 + 0.1

Combine like terms: 0 + 0.1 = 0.1
-0.8t + t2 = 0.1

The t term is -0.8t.  Take half its coefficient (-0.4).
Square it (0.16) and add it to both sides.

Add '0.16' to each side of the equation.
-0.8t + 0.16 + t2 = 0.1 + 0.16

Reorder the terms:
0.16 + -0.8t + t2 = 0.1 + 0.16

Combine like terms: 0.1 + 0.16 = 0.26
0.16 + -0.8t + t2 = 0.26

Factor a perfect square on the left side:
(t + -0.4)(t + -0.4) = 0.26

Calculate the square root of the right side: 0.509901951
