Simplifying x2 + 29x + 47 = 0 Reorder the terms: 47 + 29x + x2 = 0 Solving 47 + 29x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-47' to each side of the equation. 47 + 29x + -47 + x2 = 0 + -47 Reorder the terms: 47 + -47 + 29x + x2 = 0 + -47 Combine like terms: 47 + -47 = 0 0 + 29x + x2 = 0 + -47 29x + x2 = 0 + -47 Combine like terms: 0 + -47 = -47 29x + x2 = -47 The x term is 29x. Take half its coefficient (14.5). Square it (210.25) and add it to both sides. Add '210.25' to each side of the equation. 29x + 210.25 + x2 = -47 + 210.25 Reorder the terms: 210.25 + 29x + x2 = -47 + 210.25 Combine like terms: -47 + 210.25 = 163.25 210.25 + 29x + x2 = 163.25 Factor a perfect square on the left side: (x + 14.5)(x + 14.5) = 163.25 Calculate the square root of the right side: 12.776932339 Break this problem into two subproblems by setting (x + 14.5) equal to 12.776932339 and -12.776932339.Subproblem 1
x + 14.5 = 12.776932339 Simplifying x + 14.5 = 12.776932339 Reorder the terms: 14.5 + x = 12.776932339 Solving 14.5 + x = 12.776932339 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = 12.776932339 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = 12.776932339 + -14.5 x = 12.776932339 + -14.5 Combine like terms: 12.776932339 + -14.5 = -1.723067661 x = -1.723067661 Simplifying x = -1.723067661Subproblem 2
x + 14.5 = -12.776932339 Simplifying x + 14.5 = -12.776932339 Reorder the terms: 14.5 + x = -12.776932339 Solving 14.5 + x = -12.776932339 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14.5' to each side of the equation. 14.5 + -14.5 + x = -12.776932339 + -14.5 Combine like terms: 14.5 + -14.5 = 0.0 0.0 + x = -12.776932339 + -14.5 x = -12.776932339 + -14.5 Combine like terms: -12.776932339 + -14.5 = -27.276932339 x = -27.276932339 Simplifying x = -27.276932339Solution
