Simplifying 3(x + -2) + 2x(x + 1) = 0 Reorder the terms: 3(-2 + x) + 2x(x + 1) = 0 (-2 * 3 + x * 3) + 2x(x + 1) = 0 (-6 + 3x) + 2x(x + 1) = 0 Reorder the terms: -6 + 3x + 2x(1 + x) = 0 -6 + 3x + (1 * 2x + x * 2x) = 0 -6 + 3x + (2x + 2x2) = 0 Combine like terms: 3x + 2x = 5x -6 + 5x + 2x2 = 0 Solving -6 + 5x + 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'. -3 + 2.5x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + 2.5x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + 2.5x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2.5x + x2 = 0 + 3 2.5x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 2.5x + x2 = 3 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 3 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 3 + 1.5625 Combine like terms: 3 + 1.5625 = 4.5625 1.5625 + 2.5x + x2 = 4.5625 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 4.5625 Calculate the square root of the right side: 2.136000936 Break this problem into two subproblems by setting (x + 1.25) equal to 2.136000936 and -2.136000936.Subproblem 1
x + 1.25 = 2.136000936 Simplifying x + 1.25 = 2.136000936 Reorder the terms: 1.25 + x = 2.136000936 Solving 1.25 + x = 2.136000936 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 2.136000936 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 2.136000936 + -1.25 x = 2.136000936 + -1.25 Combine like terms: 2.136000936 + -1.25 = 0.886000936 x = 0.886000936 Simplifying x = 0.886000936Subproblem 2
x + 1.25 = -2.136000936 Simplifying x + 1.25 = -2.136000936 Reorder the terms: 1.25 + x = -2.136000936 Solving 1.25 + x = -2.136000936 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -2.136000936 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -2.136000936 + -1.25 x = -2.136000936 + -1.25 Combine like terms: -2.136000936 + -1.25 = -3.386000936 x = -3.386000936 Simplifying x = -3.386000936Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.886000936, -3.386000936}
