Add '9' to each side of the equation.
-6t + 9 + t2 = 1 + 9

Reorder the terms:
9 + -6t + t2 = 1 + 9

Combine like terms: 1 + 9 = 10
9 + -6t + t2 = 10

Factor a perfect square on the left side:
(t + -3)(t + -3) = 10

Calculate the square root of the right side: 3.16227766

Break this problem into two subproblems by setting 
(t + -3) equal to 3.16227766 and -3.16227766.

Subproblem 1

t + -3 = 3.16227766 Simplifying t + -3 = 3.16227766 Reorder the terms: -3 + t = 3.16227766 Solving -3 + t = 3.16227766 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + t = 3.16227766 + 3 Combine like terms: -3 + 3 = 0 0 + t = 3.16227766 + 3 t = 3.16227766 + 3 Combine like terms: 3.16227766 + 3 = 6.16227766 t = 6.16227766 Simplifying t = 6.16227766

Subproblem 2

t + -3 = -3.16227766 Simplifying t + -3 = -3.16227766 Reorder the terms: -3 + t = -3.16227766 Solving -3 + t = -3.16227766 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + t = -3.16227766 + 3 Combine like terms: -3 + 3 = 0 0 + t = -3.16227766 + 3 t = -3.16227766 + 3 Combine like terms: -3.16227766 + 3 = -0.16227766 t = -0.16227766 Simplifying t = -0.16227766

Solution
