-3 + -13t + 5t2 = 0 + -5t2 + 5t2
-3 + -13t + 5t2 = -5t2 + 5t2

Combine like terms: -5t2 + 5t2 = 0
-3 + -13t + 5t2 = 0

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

Divide each side by '5'.
-0.6 + -2.6t + t2 = 0

Move the constant term to the right:

Add '0.6' to each side of the equation.
-0.6 + -2.6t + 0.6 + t2 = 0 + 0.6

Reorder the terms:
-0.6 + 0.6 + -2.6t + t2 = 0 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -2.6t + t2 = 0 + 0.6
-2.6t + t2 = 0 + 0.6

Combine like terms: 0 + 0.6 = 0.6
-2.6t + t2 = 0.6

The t term is -2.6t.  Take half its coefficient (-1.3).
Square it (1.69) and add it to both sides.

Add '1.69' to each side of the equation.
-2.6t + 1.69 + t2 = 0.6 + 1.69

Reorder the terms:
1.69 + -2.6t + t2 = 0.6 + 1.69

Combine like terms: 0.6 + 1.69 = 2.29
1.69 + -2.6t + t2 = 2.29

Factor a perfect square on the left side:
(t + -1.3)(t + -1.3) = 2.29

Calculate the square root of the right side: 1.513274595

Break this problem into two subproblems by setting 
(t + -1.3) equal to 1.513274595 and -1.513274595.

Subproblem 1

t + -1.3 = 1.513274595 Simplifying t + -1.3 = 1.513274595 Reorder the terms: -1.3 + t = 1.513274595 Solving -1.3 + t = 1.513274595 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.3' to each side of the equation. -1.3 + 1.3 + t = 1.513274595 + 1.3 Combine like terms: -1.3 + 1.3 = 0.0 0.0 + t = 1.513274595 + 1.3 t = 1.513274595 + 1.3 Combine like terms: 1.513274595 + 1.3 = 2.813274595 t = 2.813274595 Simplifying t = 2.813274595

Subproblem 2

t + -1.3 = -1.513274595 Simplifying t + -1.3 = -1.513274595 Reorder the terms: -1.3 + t = -1.513274595 Solving -1.3 + t = -1.513274595 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.3' to each side of the equation. -1.3 + 1.3 + t = -1.513274595 + 1.3 Combine like terms: -1.3 + 1.3 = 0.0 0.0 + t = -1.513274595 + 1.3 t = -1.513274595 + 1.3 Combine like terms: -1.513274595 + 1.3 = -0.213274595 t = -0.213274595 Simplifying t = -0.213274595

Solution
