Subproblem 1

Set the factor '(-41 + -2t + t2)' equal to zero and attempt to solve: Simplifying -41 + -2t + t2 = 0 Solving -41 + -2t + t2 = 0 Begin completing the square. Move the constant term to the right: Add '41' to each side of the equation. -41 + -2t + 41 + t2 = 0 + 41 Reorder the terms: -41 + 41 + -2t + t2 = 0 + 41 Combine like terms: -41 + 41 = 0 0 + -2t + t2 = 0 + 41 -2t + t2 = 0 + 41 Combine like terms: 0 + 41 = 41 -2t + t2 = 41 The t term is -2t. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2t + 1 + t2 = 41 + 1 Reorder the terms: 1 + -2t + t2 = 41 + 1 Combine like terms: 41 + 1 = 42 1 + -2t + t2 = 42 Factor a perfect square on the left side: (t + -1)(t + -1) = 42 Calculate the square root of the right side: 6.480740698 Break this problem into two subproblems by setting (t + -1) equal to 6.480740698 and -6.480740698.

Subproblem 1

t + -1 = 6.480740698 Simplifying t + -1 = 6.480740698 Reorder the terms: -1 + t = 6.480740698 Solving -1 + t = 6.480740698 Solving for variable 't'.
