Simplifying x + 5x2 + 6 = 15 + -31x Reorder the terms: 6 + x + 5x2 = 15 + -31x Solving 6 + x + 5x2 = 15 + -31x Solving for variable 'x'. Reorder the terms: 6 + -15 + x + 31x + 5x2 = 15 + -31x + -15 + 31x Combine like terms: 6 + -15 = -9 -9 + x + 31x + 5x2 = 15 + -31x + -15 + 31x Combine like terms: x + 31x = 32x -9 + 32x + 5x2 = 15 + -31x + -15 + 31x Reorder the terms: -9 + 32x + 5x2 = 15 + -15 + -31x + 31x Combine like terms: 15 + -15 = 0 -9 + 32x + 5x2 = 0 + -31x + 31x -9 + 32x + 5x2 = -31x + 31x Combine like terms: -31x + 31x = 0 -9 + 32x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.8 + 6.4x + x2 = 0 Move the constant term to the right: Add '1.8' to each side of the equation. -1.8 + 6.4x + 1.8 + x2 = 0 + 1.8 Reorder the terms: -1.8 + 1.8 + 6.4x + x2 = 0 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + 6.4x + x2 = 0 + 1.8 6.4x + x2 = 0 + 1.8 Combine like terms: 0 + 1.8 = 1.8 6.4x + x2 = 1.8 The x term is 6.4x. Take half its coefficient (3.2). Square it (10.24) and add it to both sides. Add '10.24' to each side of the equation. 6.4x + 10.24 + x2 = 1.8 + 10.24 Reorder the terms: 10.24 + 6.4x + x2 = 1.8 + 10.24 Combine like terms: 1.8 + 10.24 = 12.04 10.24 + 6.4x + x2 = 12.04 Factor a perfect square on the left side: (x + 3.2)(x + 3.2) = 12.04 Calculate the square root of the right side: 3.469870315 Break this problem into two subproblems by setting (x + 3.2) equal to 3.469870315 and -3.469870315.Subproblem 1
x + 3.2 = 3.469870315 Simplifying x + 3.2 = 3.469870315 Reorder the terms: 3.2 + x = 3.469870315 Solving 3.2 + x = 3.469870315 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + x = 3.469870315 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + x = 3.469870315 + -3.2 x = 3.469870315 + -3.2 Combine like terms: 3.469870315 + -3.2 = 0.269870315 x = 0.269870315 Simplifying x = 0.269870315Subproblem 2
x + 3.2 = -3.469870315 Simplifying x + 3.2 = -3.469870315 Reorder the terms: 3.2 + x = -3.469870315 Solving 3.2 + x = -3.469870315 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.2' to each side of the equation. 3.2 + -3.2 + x = -3.469870315 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + x = -3.469870315 + -3.2 x = -3.469870315 + -3.2 Combine like terms: -3.469870315 + -3.2 = -6.669870315 x = -6.669870315 Simplifying x = -6.669870315Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.269870315, -6.669870315}
