Simplifying 16x + -139 = -2x2 Reorder the terms: -139 + 16x = -2x2 Solving -139 + 16x = -2x2 Solving for variable 'x'. Combine like terms: -2x2 + 2x2 = 0 -139 + 16x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -69.5 + 8x + x2 = 0 Move the constant term to the right: Add '69.5' to each side of the equation. -69.5 + 8x + 69.5 + x2 = 0 + 69.5 Reorder the terms: -69.5 + 69.5 + 8x + x2 = 0 + 69.5 Combine like terms: -69.5 + 69.5 = 0.0 0.0 + 8x + x2 = 0 + 69.5 8x + x2 = 0 + 69.5 Combine like terms: 0 + 69.5 = 69.5 8x + x2 = 69.5 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 = 69.5 + 16 Reorder the terms: 16 + 8x + x2 = 69.5 + 16 Combine like terms: 69.5 + 16 = 85.5 16 + 8x + x2 = 85.5 Factor a perfect square on the left side: (x + 4)(x + 4) = 85.5 Calculate the square root of the right side: 9.246621004 Break this problem into two subproblems by setting (x + 4) equal to 9.246621004 and -9.246621004.Subproblem 1
x + 4 = 9.246621004 Simplifying x + 4 = 9.246621004 Reorder the terms: 4 + x = 9.246621004 Solving 4 + x = 9.246621004 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 = 9.246621004 + -4 Combine like terms: 4 + -4 = 0 0 + x = 9.246621004 + -4 x = 9.246621004 + -4 Combine like terms: 9.246621004 + -4 = 5.246621004 x = 5.246621004 Simplifying x = 5.246621004Subproblem 2
x + 4 = -9.246621004 Simplifying x + 4 = -9.246621004 Reorder the terms: 4 + x = -9.246621004 Solving 4 + x = -9.246621004 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 = -9.246621004 + -4 Combine like terms: 4 + -4 = 0 0 + x = -9.246621004 + -4 x = -9.246621004 + -4 Combine like terms: -9.246621004 + -4 = -13.246621004 x = -13.246621004 Simplifying x = -13.246621004Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.246621004, -13.246621004}
