Simplifying x2 + x = 483 Reorder the terms: x + x2 = 483 Solving x + x2 = 483 Solving for variable 'x'. Reorder the terms: -483 + x + x2 = 483 + -483 Combine like terms: 483 + -483 = 0 -483 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '483' to each side of the equation. -483 + x + 483 + x2 = 0 + 483 Reorder the terms: -483 + 483 + x + x2 = 0 + 483 Combine like terms: -483 + 483 = 0 0 + x + x2 = 0 + 483 x + x2 = 0 + 483 Combine like terms: 0 + 483 = 483 x + x2 = 483 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 483 + 0.25 Reorder the terms: 0.25 + x + x2 = 483 + 0.25 Combine like terms: 483 + 0.25 = 483.25 0.25 + x + x2 = 483.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 483.25 Calculate the square root of the right side: 21.982947937 Break this problem into two subproblems by setting (x + 0.5) equal to 21.982947937 and -21.982947937.Subproblem 1
x + 0.5 = 21.982947937 Simplifying x + 0.5 = 21.982947937 Reorder the terms: 0.5 + x = 21.982947937 Solving 0.5 + x = 21.982947937 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 21.982947937 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 21.982947937 + -0.5 x = 21.982947937 + -0.5 Combine like terms: 21.982947937 + -0.5 = 21.482947937 x = 21.482947937 Simplifying x = 21.482947937Subproblem 2
x + 0.5 = -21.982947937 Simplifying x + 0.5 = -21.982947937 Reorder the terms: 0.5 + x = -21.982947937 Solving 0.5 + x = -21.982947937 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -21.982947937 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -21.982947937 + -0.5 x = -21.982947937 + -0.5 Combine like terms: -21.982947937 + -0.5 = -22.482947937 x = -22.482947937 Simplifying x = -22.482947937Solution
