Simplifying 0 = 15 + 8t + -5t2 Solving 0 = 15 + 8t + -5t2 Solving for variable 't'. Combine like terms: 0 + -15 = -15 -15 + -8t + 5t2 = 15 + 8t + -5t2 + -15 + -8t + 5t2 Reorder the terms: -15 + -8t + 5t2 = 15 + -15 + 8t + -8t + -5t2 + 5t2 Combine like terms: 15 + -15 = 0 -15 + -8t + 5t2 = 0 + 8t + -8t + -5t2 + 5t2 -15 + -8t + 5t2 = 8t + -8t + -5t2 + 5t2 Combine like terms: 8t + -8t = 0 -15 + -8t + 5t2 = 0 + -5t2 + 5t2 -15 + -8t + 5t2 = -5t2 + 5t2 Combine like terms: -5t2 + 5t2 = 0 -15 + -8t + 5t2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -3 + -1.6t + t2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -1.6t + 3 + t2 = 0 + 3 Reorder the terms: -3 + 3 + -1.6t + t2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1.6t + t2 = 0 + 3 -1.6t + t2 = 0 + 3 Combine like terms: 0 + 3 = 3 -1.6t + t2 = 3 The t term is -1.6t. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6t + 0.64 + t2 = 3 + 0.64 Reorder the terms: 0.64 + -1.6t + t2 = 3 + 0.64 Combine like terms: 3 + 0.64 = 3.64 0.64 + -1.6t + t2 = 3.64 Factor a perfect square on the left side: (t + -0.8)(t + -0.8) = 3.64 Calculate the square root of the right side: 1.907878403 Break this problem into two subproblems by setting (t + -0.8) equal to 1.907878403 and -1.907878403.Subproblem 1
t + -0.8 = 1.907878403 Simplifying t + -0.8 = 1.907878403 Reorder the terms: -0.8 + t = 1.907878403 Solving -0.8 + t = 1.907878403 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + t = 1.907878403 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = 1.907878403 + 0.8 t = 1.907878403 + 0.8 Combine like terms: 1.907878403 + 0.8 = 2.707878403 t = 2.707878403 Simplifying t = 2.707878403Subproblem 2
t + -0.8 = -1.907878403 Simplifying t + -0.8 = -1.907878403 Reorder the terms: -0.8 + t = -1.907878403 Solving -0.8 + t = -1.907878403 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + t = -1.907878403 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = -1.907878403 + 0.8 t = -1.907878403 + 0.8 Combine like terms: -1.907878403 + 0.8 = -1.107878403 t = -1.107878403 Simplifying t = -1.107878403Solution
The solution to the problem is based on the solutions from the subproblems. t = {2.707878403, -1.107878403}
