-0.2 the coefficient of the squared term: 

Divide each side by '-0.2'.
88 + -26t + t2 = 0

Move the constant term to the right:

Add '-88' to each side of the equation.
88 + -26t + -88 + t2 = 0 + -88

Reorder the terms:
88 + -88 + -26t + t2 = 0 + -88

Combine like terms: 88 + -88 = 0
0 + -26t + t2 = 0 + -88
-26t + t2 = 0 + -88

Combine like terms: 0 + -88 = -88
-26t + t2 = -88

The t term is -26t.  Take half its coefficient (-13).
Square it (169) and add it to both sides.

Add '169' to each side of the equation.
-26t + 169 + t2 = -88 + 169

Reorder the terms:
169 + -26t + t2 = -88 + 169

Combine like terms: -88 + 169 = 81
169 + -26t + t2 = 81

Factor a perfect square on the left side:
(t + -13)(t + -13) = 81

Calculate the square root of the right side: 9

Break this problem into two subproblems by setting 
(t + -13) equal to 9 and -9.

Subproblem 1

t + -13 = 9 Simplifying t + -13 = 9 Reorder the terms: -13 + t = 9 Solving -13 + t = 9 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + t = 9 + 13 Combine like terms: -13 + 13 = 0 0 + t = 9 + 13 t = 9 + 13 Combine like terms: 9 + 13 = 22 t = 22 Simplifying t = 22

Subproblem 2

t + -13 = -9 Simplifying t + -13 = -9 Reorder the terms: -13 + t = -9 Solving -13 + t = -9 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + t = -9 + 13 Combine like terms: -13 + 13 = 0 0 + t = -9 + 13 t = -9 + 13 Combine like terms: -9 + 13 = 4 t = 4 Simplifying t = 4

Solution

The solution to the problem is based on the solutions from the subproblems. t = {22, 4}
