Simplifying 2x2 + 16x + -31 = 0 Reorder the terms: -31 + 16x + 2x2 = 0 Solving -31 + 16x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -15.5 + 8x + x2 = 0 Move the constant term to the right: Add '15.5' to each side of the equation. -15.5 + 8x + 15.5 + x2 = 0 + 15.5 Reorder the terms: -15.5 + 15.5 + 8x + x2 = 0 + 15.5 Combine like terms: -15.5 + 15.5 = 0.0 0.0 + 8x + x2 = 0 + 15.5 8x + x2 = 0 + 15.5 Combine like terms: 0 + 15.5 = 15.5 8x + x2 = 15.5 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 15.5 + 16 Reorder the terms: 16 + 8x + x2 = 15.5 + 16 Combine like terms: 15.5 + 16 = 31.5 16 + 8x + x2 = 31.5 Factor a perfect square on the left side: (x + 4)(x + 4) = 31.5 Calculate the square root of the right side: 5.61248608 Break this problem into two subproblems by setting (x + 4) equal to 5.61248608 and -5.61248608.Subproblem 1
x + 4 = 5.61248608 Simplifying x + 4 = 5.61248608 Reorder the terms: 4 + x = 5.61248608 Solving 4 + x = 5.61248608 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 5.61248608 + -4 Combine like terms: 4 + -4 = 0 0 + x = 5.61248608 + -4 x = 5.61248608 + -4 Combine like terms: 5.61248608 + -4 = 1.61248608 x = 1.61248608 Simplifying x = 1.61248608Subproblem 2
x + 4 = -5.61248608 Simplifying x + 4 = -5.61248608 Reorder the terms: 4 + x = -5.61248608 Solving 4 + x = -5.61248608 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -5.61248608 + -4 Combine like terms: 4 + -4 = 0 0 + x = -5.61248608 + -4 x = -5.61248608 + -4 Combine like terms: -5.61248608 + -4 = -9.61248608 x = -9.61248608 Simplifying x = -9.61248608Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.61248608, -9.61248608}
