Simplifying 4x2 + 8x + -23 = 0 Reorder the terms: -23 + 8x + 4x2 = 0 Solving -23 + 8x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -5.75 + 2x + x2 = 0 Move the constant term to the right: Add '5.75' to each side of the equation. -5.75 + 2x + 5.75 + x2 = 0 + 5.75 Reorder the terms: -5.75 + 5.75 + 2x + x2 = 0 + 5.75 Combine like terms: -5.75 + 5.75 = 0.00 0.00 + 2x + x2 = 0 + 5.75 2x + x2 = 0 + 5.75 Combine like terms: 0 + 5.75 = 5.75 2x + x2 = 5.75 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 5.75 + 1 Reorder the terms: 1 + 2x + x2 = 5.75 + 1 Combine like terms: 5.75 + 1 = 6.75 1 + 2x + x2 = 6.75 Factor a perfect square on the left side: (x + 1)(x + 1) = 6.75 Calculate the square root of the right side: 2.598076211 Break this problem into two subproblems by setting (x + 1) equal to 2.598076211 and -2.598076211.Subproblem 1
x + 1 = 2.598076211 Simplifying x + 1 = 2.598076211 Reorder the terms: 1 + x = 2.598076211 Solving 1 + x = 2.598076211 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 2.598076211 + -1 Combine like terms: 1 + -1 = 0 0 + x = 2.598076211 + -1 x = 2.598076211 + -1 Combine like terms: 2.598076211 + -1 = 1.598076211 x = 1.598076211 Simplifying x = 1.598076211Subproblem 2
x + 1 = -2.598076211 Simplifying x + 1 = -2.598076211 Reorder the terms: 1 + x = -2.598076211 Solving 1 + x = -2.598076211 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -2.598076211 + -1 Combine like terms: 1 + -1 = 0 0 + x = -2.598076211 + -1 x = -2.598076211 + -1 Combine like terms: -2.598076211 + -1 = -3.598076211 x = -3.598076211 Simplifying x = -3.598076211Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.598076211, -3.598076211}
