Solving for variable 't'.

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
-16 + -0.6t + t2 = 0

Move the constant term to the right:

Add '16' to each side of the equation.
-16 + -0.6t + 16 + t2 = 0 + 16

Reorder the terms:
-16 + 16 + -0.6t + t2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + -0.6t + t2 = 0 + 16
-0.6t + t2 = 0 + 16

Combine like terms: 0 + 16 = 16
-0.6t + t2 = 16

The t term is -0.6t.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6t + 0.09 + t2 = 16 + 0.09

Reorder the terms:
0.09 + -0.6t + t2 = 16 + 0.09

Combine like terms: 16 + 0.09 = 16.09
0.09 + -0.6t + t2 = 16.09

Factor a perfect square on the left side:
(t + -0.3)(t + -0.3) = 16.09

Calculate the square root of the right side: 4.011234224
