Simplifying 1 + 9t + 5t2 = 0 Solving 1 + 9t + 5t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.2 + 1.8t + t2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + 1.8t + -0.2 + t2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + 1.8t + t2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + 1.8t + t2 = 0 + -0.2 1.8t + t2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 1.8t + t2 = -0.2 The t term is 1.8t. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8t + 0.81 + t2 = -0.2 + 0.81 Reorder the terms: 0.81 + 1.8t + t2 = -0.2 + 0.81 Combine like terms: -0.2 + 0.81 = 0.61 0.81 + 1.8t + t2 = 0.61 Factor a perfect square on the left side: (t + 0.9)(t + 0.9) = 0.61 Calculate the square root of the right side: 0.781024968 Break this problem into two subproblems by setting (t + 0.9) equal to 0.781024968 and -0.781024968.Subproblem 1
t + 0.9 = 0.781024968 Simplifying t + 0.9 = 0.781024968 Reorder the terms: 0.9 + t = 0.781024968 Solving 0.9 + t = 0.781024968 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + t = 0.781024968 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + t = 0.781024968 + -0.9 t = 0.781024968 + -0.9 Combine like terms: 0.781024968 + -0.9 = -0.118975032 t = -0.118975032 Simplifying t = -0.118975032Subproblem 2
t + 0.9 = -0.781024968 Simplifying t + 0.9 = -0.781024968 Reorder the terms: 0.9 + t = -0.781024968 Solving 0.9 + t = -0.781024968 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + t = -0.781024968 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + t = -0.781024968 + -0.9 t = -0.781024968 + -0.9 Combine like terms: -0.781024968 + -0.9 = -1.681024968 t = -1.681024968 Simplifying t = -1.681024968Solution
The solution to the problem is based on the solutions from the subproblems. t = {-0.118975032, -1.681024968}
