Simplifying 2l2 + 14l + -123 = 0 Reorder the terms: -123 + 14l + 2l2 = 0 Solving -123 + 14l + 2l2 = 0 Solving for variable 'l'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -61.5 + 7l + l2 = 0 Move the constant term to the right: Add '61.5' to each side of the equation. -61.5 + 7l + 61.5 + l2 = 0 + 61.5 Reorder the terms: -61.5 + 61.5 + 7l + l2 = 0 + 61.5 Combine like terms: -61.5 + 61.5 = 0.0 0.0 + 7l + l2 = 0 + 61.5 7l + l2 = 0 + 61.5 Combine like terms: 0 + 61.5 = 61.5 7l + l2 = 61.5 The l term is 7l. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7l + 12.25 + l2 = 61.5 + 12.25 Reorder the terms: 12.25 + 7l + l2 = 61.5 + 12.25 Combine like terms: 61.5 + 12.25 = 73.75 12.25 + 7l + l2 = 73.75 Factor a perfect square on the left side: (l + 3.5)(l + 3.5) = 73.75 Calculate the square root of the right side: 8.587782019 Break this problem into two subproblems by setting (l + 3.5) equal to 8.587782019 and -8.587782019.Subproblem 1
l + 3.5 = 8.587782019 Simplifying l + 3.5 = 8.587782019 Reorder the terms: 3.5 + l = 8.587782019 Solving 3.5 + l = 8.587782019 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + l = 8.587782019 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + l = 8.587782019 + -3.5 l = 8.587782019 + -3.5 Combine like terms: 8.587782019 + -3.5 = 5.087782019 l = 5.087782019 Simplifying l = 5.087782019Subproblem 2
l + 3.5 = -8.587782019 Simplifying l + 3.5 = -8.587782019 Reorder the terms: 3.5 + l = -8.587782019 Solving 3.5 + l = -8.587782019 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + l = -8.587782019 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + l = -8.587782019 + -3.5 l = -8.587782019 + -3.5 Combine like terms: -8.587782019 + -3.5 = -12.087782019 l = -12.087782019 Simplifying l = -12.087782019Solution
The solution to the problem is based on the solutions from the subproblems. l = {5.087782019, -12.087782019}
