Simplifying x2 + 3x = 90000 Reorder the terms: 3x + x2 = 90000 Solving 3x + x2 = 90000 Solving for variable 'x'. Reorder the terms: -90000 + 3x + x2 = 90000 + -90000 Combine like terms: 90000 + -90000 = 0 -90000 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '90000' to each side of the equation. -90000 + 3x + 90000 + x2 = 0 + 90000 Reorder the terms: -90000 + 90000 + 3x + x2 = 0 + 90000 Combine like terms: -90000 + 90000 = 0 0 + 3x + x2 = 0 + 90000 3x + x2 = 0 + 90000 Combine like terms: 0 + 90000 = 90000 3x + x2 = 90000 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 90000 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 90000 + 2.25 Combine like terms: 90000 + 2.25 = 90002.25 2.25 + 3x + x2 = 90002.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 90002.25 Calculate the square root of the right side: 300.003749977 Break this problem into two subproblems by setting (x + 1.5) equal to 300.003749977 and -300.003749977.Subproblem 1
x + 1.5 = 300.003749977 Simplifying x + 1.5 = 300.003749977 Reorder the terms: 1.5 + x = 300.003749977 Solving 1.5 + x = 300.003749977 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 300.003749977 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 300.003749977 + -1.5 x = 300.003749977 + -1.5 Combine like terms: 300.003749977 + -1.5 = 298.503749977 x = 298.503749977 Simplifying x = 298.503749977Subproblem 2
x + 1.5 = -300.003749977 Simplifying x + 1.5 = -300.003749977 Reorder the terms: 1.5 + x = -300.003749977 Solving 1.5 + x = -300.003749977 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -300.003749977 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -300.003749977 + -1.5 x = -300.003749977 + -1.5 Combine like terms: -300.003749977 + -1.5 = -301.503749977 x = -301.503749977 Simplifying x = -301.503749977Solution
The solution to the problem is based on the solutions from the subproblems. x = {298.503749977, -301.503749977}
