Simplifying x2 + 23x + -280 = 0 Reorder the terms: -280 + 23x + x2 = 0 Solving -280 + 23x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '280' to each side of the equation. -280 + 23x + 280 + x2 = 0 + 280 Reorder the terms: -280 + 280 + 23x + x2 = 0 + 280 Combine like terms: -280 + 280 = 0 0 + 23x + x2 = 0 + 280 23x + x2 = 0 + 280 Combine like terms: 0 + 280 = 280 23x + x2 = 280 The x term is 23x. Take half its coefficient (11.5). Square it (132.25) and add it to both sides. Add '132.25' to each side of the equation. 23x + 132.25 + x2 = 280 + 132.25 Reorder the terms: 132.25 + 23x + x2 = 280 + 132.25 Combine like terms: 280 + 132.25 = 412.25 132.25 + 23x + x2 = 412.25 Factor a perfect square on the left side: (x + 11.5)(x + 11.5) = 412.25 Calculate the square root of the right side: 20.303940504 Break this problem into two subproblems by setting (x + 11.5) equal to 20.303940504 and -20.303940504.Subproblem 1
x + 11.5 = 20.303940504 Simplifying x + 11.5 = 20.303940504 Reorder the terms: 11.5 + x = 20.303940504 Solving 11.5 + x = 20.303940504 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11.5' to each side of the equation. 11.5 + -11.5 + x = 20.303940504 + -11.5 Combine like terms: 11.5 + -11.5 = 0.0 0.0 + x = 20.303940504 + -11.5 x = 20.303940504 + -11.5 Combine like terms: 20.303940504 + -11.5 = 8.803940504 x = 8.803940504 Simplifying x = 8.803940504Subproblem 2
x + 11.5 = -20.303940504 Simplifying x + 11.5 = -20.303940504 Reorder the terms: 11.5 + x = -20.303940504 Solving 11.5 + x = -20.303940504 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11.5' to each side of the equation. 11.5 + -11.5 + x = -20.303940504 + -11.5 Combine like terms: 11.5 + -11.5 = 0.0 0.0 + x = -20.303940504 + -11.5 x = -20.303940504 + -11.5 Combine like terms: -20.303940504 + -11.5 = -31.803940504 x = -31.803940504 Simplifying x = -31.803940504Solution
