Simplifying 2t2 + -12t + -9 = 0 Reorder the terms: -9 + -12t + 2t2 = 0 Solving -9 + -12t + 2t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -4.5 + -6t + t2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + -6t + 4.5 + t2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + -6t + t2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + -6t + t2 = 0 + 4.5 -6t + t2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 -6t + t2 = 4.5 The t term is -6t. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6t + 9 + t2 = 4.5 + 9 Reorder the terms: 9 + -6t + t2 = 4.5 + 9 Combine like terms: 4.5 + 9 = 13.5 9 + -6t + t2 = 13.5 Factor a perfect square on the left side: (t + -3)(t + -3) = 13.5 Calculate the square root of the right side: 3.674234614 Break this problem into two subproblems by setting (t + -3) equal to 3.674234614 and -3.674234614.Subproblem 1
t + -3 = 3.674234614 Simplifying t + -3 = 3.674234614 Reorder the terms: -3 + t = 3.674234614 Solving -3 + t = 3.674234614 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 = 3.674234614 + 3 Combine like terms: -3 + 3 = 0 0 + t = 3.674234614 + 3 t = 3.674234614 + 3 Combine like terms: 3.674234614 + 3 = 6.674234614 t = 6.674234614 Simplifying t = 6.674234614Subproblem 2
t + -3 = -3.674234614 Simplifying t + -3 = -3.674234614 Reorder the terms: -3 + t = -3.674234614 Solving -3 + t = -3.674234614 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 = -3.674234614 + 3 Combine like terms: -3 + 3 = 0 0 + t = -3.674234614 + 3 t = -3.674234614 + 3 Combine like terms: -3.674234614 + 3 = -0.674234614 t = -0.674234614 Simplifying t = -0.674234614Solution
