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 = 4.5 9 + -6t + t2 = 4.5 Factor a perfect square on the left side: (t + -3)(t + -3) = 4.5 Calculate the square root of the right side: 2.121320344 Break this problem into two subproblems by setting (t + -3) equal to 2.121320344 and -2.121320344.Subproblem 1
t + -3 = 2.121320344 Simplifying t + -3 = 2.121320344 Reorder the terms: -3 + t = 2.121320344 Solving -3 + t = 2.121320344 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 = 2.121320344 + 3 Combine like terms: -3 + 3 = 0 0 + t = 2.121320344 + 3 t = 2.121320344 + 3 Combine like terms: 2.121320344 + 3 = 5.121320344 t = 5.121320344 Simplifying t = 5.121320344Subproblem 2
t + -3 = -2.121320344 Simplifying t + -3 = -2.121320344 Reorder the terms: -3 + t = -2.121320344 Solving -3 + t = -2.121320344 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 = -2.121320344 + 3 Combine like terms: -3 + 3 = 0 0 + t = -2.121320344 + 3 t = -2.121320344 + 3 Combine like terms: -2.121320344 + 3 = 0.878679656 t = 0.878679656 Simplifying t = 0.878679656Solution
