Simplifying x2 + 32x + 23 = 0 Reorder the terms: 23 + 32x + x2 = 0 Solving 23 + 32x + 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 + 32x + -23 + x2 = 0 + -23 Reorder the terms: 23 + -23 + 32x + x2 = 0 + -23 Combine like terms: 23 + -23 = 0 0 + 32x + x2 = 0 + -23 32x + x2 = 0 + -23 Combine like terms: 0 + -23 = -23 32x + x2 = -23 The x term is 32x. Take half its coefficient (16). Square it (256) and add it to both sides. Add '256' to each side of the equation. 32x + 256 + x2 = -23 + 256 Reorder the terms: 256 + 32x + x2 = -23 + 256 Combine like terms: -23 + 256 = 233 256 + 32x + x2 = 233 Factor a perfect square on the left side: (x + 16)(x + 16) = 233 Calculate the square root of the right side: 15.264337522 Break this problem into two subproblems by setting (x + 16) equal to 15.264337522 and -15.264337522.Subproblem 1
x + 16 = 15.264337522 Simplifying x + 16 = 15.264337522 Reorder the terms: 16 + x = 15.264337522 Solving 16 + x = 15.264337522 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + x = 15.264337522 + -16 Combine like terms: 16 + -16 = 0 0 + x = 15.264337522 + -16 x = 15.264337522 + -16 Combine like terms: 15.264337522 + -16 = -0.735662478 x = -0.735662478 Simplifying x = -0.735662478Subproblem 2
x + 16 = -15.264337522 Simplifying x + 16 = -15.264337522 Reorder the terms: 16 + x = -15.264337522 Solving 16 + x = -15.264337522 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + x = -15.264337522 + -16 Combine like terms: 16 + -16 = 0 0 + x = -15.264337522 + -16 x = -15.264337522 + -16 Combine like terms: -15.264337522 + -16 = -31.264337522 x = -31.264337522 Simplifying x = -31.264337522Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.735662478, -31.264337522}
