Simplifying (x + 2)(x + -5) + -9x = 0 Reorder the terms: (2 + x)(x + -5) + -9x = 0 Reorder the terms: (2 + x)(-5 + x) + -9x = 0 Multiply (2 + x) * (-5 + x) (2(-5 + x) + x(-5 + x)) + -9x = 0 ((-5 * 2 + x * 2) + x(-5 + x)) + -9x = 0 ((-10 + 2x) + x(-5 + x)) + -9x = 0 (-10 + 2x + (-5 * x + x * x)) + -9x = 0 (-10 + 2x + (-5x + x2)) + -9x = 0 Combine like terms: 2x + -5x = -3x (-10 + -3x + x2) + -9x = 0 Reorder the terms: -10 + -3x + -9x + x2 = 0 Combine like terms: -3x + -9x = -12x -10 + -12x + x2 = 0 Solving -10 + -12x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + -12x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + -12x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -12x + x2 = 0 + 10 -12x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 -12x + x2 = 10 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = 10 + 36 Reorder the terms: 36 + -12x + x2 = 10 + 36 Combine like terms: 10 + 36 = 46 36 + -12x + x2 = 46 Factor a perfect square on the left side: (x + -6)(x + -6) = 46 Calculate the square root of the right side: 6.782329983 Break this problem into two subproblems by setting (x + -6) equal to 6.782329983 and -6.782329983.Subproblem 1
x + -6 = 6.782329983 Simplifying x + -6 = 6.782329983 Reorder the terms: -6 + x = 6.782329983 Solving -6 + x = 6.782329983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 6.782329983 + 6 Combine like terms: -6 + 6 = 0 0 + x = 6.782329983 + 6 x = 6.782329983 + 6 Combine like terms: 6.782329983 + 6 = 12.782329983 x = 12.782329983 Simplifying x = 12.782329983Subproblem 2
x + -6 = -6.782329983 Simplifying x + -6 = -6.782329983 Reorder the terms: -6 + x = -6.782329983 Solving -6 + x = -6.782329983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = -6.782329983 + 6 Combine like terms: -6 + 6 = 0 0 + x = -6.782329983 + 6 x = -6.782329983 + 6 Combine like terms: -6.782329983 + 6 = -0.782329983 x = -0.782329983 Simplifying x = -0.782329983Solution
The solution to the problem is based on the solutions from the subproblems. x = {12.782329983, -0.782329983}
