Simplifying x(2x + 54) = x + -1x + 500 Reorder the terms: x(54 + 2x) = x + -1x + 500 (54 * x + 2x * x) = x + -1x + 500 (54x + 2x2) = x + -1x + 500 Reorder the terms: 54x + 2x2 = 500 + x + -1x Combine like terms: x + -1x = 0 54x + 2x2 = 500 + 0 54x + 2x2 = 500 Solving 54x + 2x2 = 500 Solving for variable 'x'. Reorder the terms: -500 + 54x + 2x2 = 500 + -500 Combine like terms: 500 + -500 = 0 -500 + 54x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-250 + 27x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-250 + 27x + x2)' equal to zero and attempt to solve: Simplifying -250 + 27x + x2 = 0 Solving -250 + 27x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '250' to each side of the equation. -250 + 27x + 250 + x2 = 0 + 250 Reorder the terms: -250 + 250 + 27x + x2 = 0 + 250 Combine like terms: -250 + 250 = 0 0 + 27x + x2 = 0 + 250 27x + x2 = 0 + 250 Combine like terms: 0 + 250 = 250 27x + x2 = 250 The x term is 27x. Take half its coefficient (13.5). Square it (182.25) and add it to both sides. Add '182.25' to each side of the equation. 27x + 182.25 + x2 = 250 + 182.25 Reorder the terms: 182.25 + 27x + x2 = 250 + 182.25 Combine like terms: 250 + 182.25 = 432.25 182.25 + 27x + x2 = 432.25 Factor a perfect square on the left side: (x + 13.5)(x + 13.5) = 432.25 Calculate the square root of the right side: 20.790622886 Break this problem into two subproblems by setting (x + 13.5) equal to 20.790622886 and -20.790622886.Subproblem 1
x + 13.5 = 20.790622886 Simplifying x + 13.5 = 20.790622886 Reorder the terms: 13.5 + x = 20.790622886 Solving 13.5 + x = 20.790622886 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + x = 20.790622886 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = 20.790622886 + -13.5 x = 20.790622886 + -13.5 Combine like terms: 20.790622886 + -13.5 = 7.290622886 x = 7.290622886 Simplifying x = 7.290622886Subproblem 2
x + 13.5 = -20.790622886 Simplifying x + 13.5 = -20.790622886 Reorder the terms: 13.5 + x = -20.790622886 Solving 13.5 + x = -20.790622886 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-13.5' to each side of the equation. 13.5 + -13.5 + x = -20.790622886 + -13.5 Combine like terms: 13.5 + -13.5 = 0.0 0.0 + x = -20.790622886 + -13.5 x = -20.790622886 + -13.5 Combine like terms: -20.790622886 + -13.5 = -34.290622886 x = -34.290622886 Simplifying x = -34.290622886Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.290622886, -34.290622886}Solution
x = {7.290622886, -34.290622886}
