Simplifying x2 + 1x = 21 Reorder the terms: 1x + x2 = 21 Solving 1x + x2 = 21 Solving for variable 'x'. Reorder the terms: -21 + 1x + x2 = 21 + -21 Combine like terms: 21 + -21 = 0 -21 + 1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + 1x + 21 + x2 = 0 + 21 Reorder the terms: -21 + 21 + 1x + x2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 1x + x2 = 0 + 21 1x + x2 = 0 + 21 Combine like terms: 0 + 21 = 21 1x + x2 = 21 The x term is 1x. 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 = 21 + 0.25 Reorder the terms: 0.25 + x + x2 = 21 + 0.25 Combine like terms: 21 + 0.25 = 21.25 0.25 + x + x2 = 21.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 21.25 Calculate the square root of the right side: 4.609772229 Break this problem into two subproblems by setting (x + 0.5) equal to 4.609772229 and -4.609772229.Subproblem 1
x + 0.5 = 4.609772229 Simplifying x + 0.5 = 4.609772229 Reorder the terms: 0.5 + x = 4.609772229 Solving 0.5 + x = 4.609772229 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 = 4.609772229 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 4.609772229 + -0.5 x = 4.609772229 + -0.5 Combine like terms: 4.609772229 + -0.5 = 4.109772229 x = 4.109772229 Simplifying x = 4.109772229Subproblem 2
x + 0.5 = -4.609772229 Simplifying x + 0.5 = -4.609772229 Reorder the terms: 0.5 + x = -4.609772229 Solving 0.5 + x = -4.609772229 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 = -4.609772229 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -4.609772229 + -0.5 x = -4.609772229 + -0.5 Combine like terms: -4.609772229 + -0.5 = -5.109772229 x = -5.109772229 Simplifying x = -5.109772229Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.109772229, -5.109772229}
