Simplifying 2t2 + -7t + -8 = 0 Reorder the terms: -8 + -7t + 2t2 = 0 Solving -8 + -7t + 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 + -3.5t + t2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + -3.5t + 4 + t2 = 0 + 4 Reorder the terms: -4 + 4 + -3.5t + t2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -3.5t + t2 = 0 + 4 -3.5t + t2 = 0 + 4 Combine like terms: 0 + 4 = 4 -3.5t + t2 = 4 The t term is -3.5t. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5t + 3.0625 + t2 = 4 + 3.0625 Reorder the terms: 3.0625 + -3.5t + t2 = 4 + 3.0625 Combine like terms: 4 + 3.0625 = 7.0625 3.0625 + -3.5t + t2 = 7.0625 Factor a perfect square on the left side: (t + -1.75)(t + -1.75) = 7.0625 Calculate the square root of the right side: 2.657536453 Break this problem into two subproblems by setting (t + -1.75) equal to 2.657536453 and -2.657536453.Subproblem 1
t + -1.75 = 2.657536453 Simplifying t + -1.75 = 2.657536453 Reorder the terms: -1.75 + t = 2.657536453 Solving -1.75 + t = 2.657536453 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + t = 2.657536453 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + t = 2.657536453 + 1.75 t = 2.657536453 + 1.75 Combine like terms: 2.657536453 + 1.75 = 4.407536453 t = 4.407536453 Simplifying t = 4.407536453Subproblem 2
t + -1.75 = -2.657536453 Simplifying t + -1.75 = -2.657536453 Reorder the terms: -1.75 + t = -2.657536453 Solving -1.75 + t = -2.657536453 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + t = -2.657536453 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + t = -2.657536453 + 1.75 t = -2.657536453 + 1.75 Combine like terms: -2.657536453 + 1.75 = -0.907536453 t = -0.907536453 Simplifying t = -0.907536453Solution
