Simplifying x2 + 16x + -23 = 0 Reorder the terms: -23 + 16x + x2 = 0 Solving -23 + 16x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '23' to each side of the equation. -23 + 16x + 23 + x2 = 0 + 23 Reorder the terms: -23 + 23 + 16x + x2 = 0 + 23 Combine like terms: -23 + 23 = 0 0 + 16x + x2 = 0 + 23 16x + x2 = 0 + 23 Combine like terms: 0 + 23 = 23 16x + x2 = 23 The x term is 16x. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16x + 64 + x2 = 23 + 64 Reorder the terms: 64 + 16x + x2 = 23 + 64 Combine like terms: 23 + 64 = 87 64 + 16x + x2 = 87 Factor a perfect square on the left side: (x + 8)(x + 8) = 87 Calculate the square root of the right side: 9.327379053 Break this problem into two subproblems by setting (x + 8) equal to 9.327379053 and -9.327379053.Subproblem 1
x + 8 = 9.327379053 Simplifying x + 8 = 9.327379053 Reorder the terms: 8 + x = 9.327379053 Solving 8 + x = 9.327379053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = 9.327379053 + -8 Combine like terms: 8 + -8 = 0 0 + x = 9.327379053 + -8 x = 9.327379053 + -8 Combine like terms: 9.327379053 + -8 = 1.327379053 x = 1.327379053 Simplifying x = 1.327379053Subproblem 2
x + 8 = -9.327379053 Simplifying x + 8 = -9.327379053 Reorder the terms: 8 + x = -9.327379053 Solving 8 + x = -9.327379053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = -9.327379053 + -8 Combine like terms: 8 + -8 = 0 0 + x = -9.327379053 + -8 x = -9.327379053 + -8 Combine like terms: -9.327379053 + -8 = -17.327379053 x = -17.327379053 Simplifying x = -17.327379053Solution
