Solving
-3 + -11t + 5t2 = 0

Solving for variable 't'.

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

Divide each side by '5'.
-0.6 + -2.2t + t2 = 0

Move the constant term to the right:

Add '0.6' to each side of the equation.
-0.6 + -2.2t + 0.6 + t2 = 0 + 0.6

Reorder the terms:
-0.6 + 0.6 + -2.2t + t2 = 0 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -2.2t + t2 = 0 + 0.6
-2.2t + t2 = 0 + 0.6

Combine like terms: 0 + 0.6 = 0.6
-2.2t + t2 = 0.6

The t term is -2.2t.  Take half its coefficient (-1.1).
Square it (1.21) and add it to both sides.

Add '1.21' to each side of the equation.
-2.2t + 1.21 + t2 = 0.6 + 1.21

Reorder the terms:
1.21 + -2.2t + t2 = 0.6 + 1.21

Combine like terms: 0.6 + 1.21 = 1.81
1.21 + -2.2t + t2 = 1.81

Factor a perfect square on the left side:
(t + -1.1)(t + -1.1) = 1.81

Calculate the square root of the right side: 1.345362405

Break this problem into two subproblems by setting 
(t + -1.1) equal to 1.345362405 and -1.345362405.

Subproblem 1

t + -1.1 = 1.345362405 Simplifying t + -1.1 = 1.345362405 Reorder the terms: -1.1 + t = 1.345362405 Solving -1.1 + t = 1.345362405 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + t = 1.345362405 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + t = 1.345362405 + 1.1 t = 1.345362405 + 1.1 Combine like terms: 1.345362405 + 1.1 = 2.445362405 t = 2.445362405 Simplifying t = 2.445362405

Subproblem 2

t + -1.1 = -1.345362405 Simplifying t + -1.1 = -1.345362405 Reorder the terms: -1.1 + t = -1.345362405 Solving -1.1 + t = -1.345362405 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + t = -1.345362405 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + t = -1.345362405 + 1.1 t = -1.345362405 + 1.1 Combine like terms: -1.345362405 + 1.1 = -0.245362405 t = -0.245362405 Simplifying t = -0.245362405
