Simplifying 2x(x + 5) = x + -8 Reorder the terms: 2x(5 + x) = x + -8 (5 * 2x + x * 2x) = x + -8 (10x + 2x2) = x + -8 Reorder the terms: 10x + 2x2 = -8 + x Solving 10x + 2x2 = -8 + x Solving for variable 'x'. Reorder the terms: 8 + 10x + -1x + 2x2 = -8 + x + 8 + -1x Combine like terms: 10x + -1x = 9x 8 + 9x + 2x2 = -8 + x + 8 + -1x Reorder the terms: 8 + 9x + 2x2 = -8 + 8 + x + -1x Combine like terms: -8 + 8 = 0 8 + 9x + 2x2 = 0 + x + -1x 8 + 9x + 2x2 = x + -1x Combine like terms: x + -1x = 0 8 + 9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 4 + 4.5x + x2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 4.5x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 4.5x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 4.5x + x2 = 0 + -4 4.5x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 4.5x + x2 = -4 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = -4 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = -4 + 5.0625 Combine like terms: -4 + 5.0625 = 1.0625 5.0625 + 4.5x + x2 = 1.0625 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (x + 2.25) equal to 1.030776406 and -1.030776406.Subproblem 1
x + 2.25 = 1.030776406 Simplifying x + 2.25 = 1.030776406 Reorder the terms: 2.25 + x = 1.030776406 Solving 2.25 + x = 1.030776406 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = 1.030776406 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = 1.030776406 + -2.25 x = 1.030776406 + -2.25 Combine like terms: 1.030776406 + -2.25 = -1.219223594 x = -1.219223594 Simplifying x = -1.219223594Subproblem 2
x + 2.25 = -1.030776406 Simplifying x + 2.25 = -1.030776406 Reorder the terms: 2.25 + x = -1.030776406 Solving 2.25 + x = -1.030776406 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = -1.030776406 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = -1.030776406 + -2.25 x = -1.030776406 + -2.25 Combine like terms: -1.030776406 + -2.25 = -3.280776406 x = -3.280776406 Simplifying x = -3.280776406Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.219223594, -3.280776406}
