Simplifying l2 + -5l = 18 Reorder the terms: -5l + l2 = 18 Solving -5l + l2 = 18 Solving for variable 'l'. Reorder the terms: -18 + -5l + l2 = 18 + -18 Combine like terms: 18 + -18 = 0 -18 + -5l + l2 = 0 Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + -5l + 18 + l2 = 0 + 18 Reorder the terms: -18 + 18 + -5l + l2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -5l + l2 = 0 + 18 -5l + l2 = 0 + 18 Combine like terms: 0 + 18 = 18 -5l + l2 = 18 The l term is -5l. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5l + 6.25 + l2 = 18 + 6.25 Reorder the terms: 6.25 + -5l + l2 = 18 + 6.25 Combine like terms: 18 + 6.25 = 24.25 6.25 + -5l + l2 = 24.25 Factor a perfect square on the left side: (l + -2.5)(l + -2.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (l + -2.5) equal to 4.924428901 and -4.924428901.Subproblem 1
l + -2.5 = 4.924428901 Simplifying l + -2.5 = 4.924428901 Reorder the terms: -2.5 + l = 4.924428901 Solving -2.5 + l = 4.924428901 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + l = 4.924428901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + l = 4.924428901 + 2.5 l = 4.924428901 + 2.5 Combine like terms: 4.924428901 + 2.5 = 7.424428901 l = 7.424428901 Simplifying l = 7.424428901Subproblem 2
l + -2.5 = -4.924428901 Simplifying l + -2.5 = -4.924428901 Reorder the terms: -2.5 + l = -4.924428901 Solving -2.5 + l = -4.924428901 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + l = -4.924428901 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + l = -4.924428901 + 2.5 l = -4.924428901 + 2.5 Combine like terms: -4.924428901 + 2.5 = -2.424428901 l = -2.424428901 Simplifying l = -2.424428901Solution
The solution to the problem is based on the solutions from the subproblems. l = {7.424428901, -2.424428901}
