Simplifying (x + 2)(x + -5) = 56 Reorder the terms: (2 + x)(x + -5) = 56 Reorder the terms: (2 + x)(-5 + x) = 56 Multiply (2 + x) * (-5 + x) (2(-5 + x) + x(-5 + x)) = 56 ((-5 * 2 + x * 2) + x(-5 + x)) = 56 ((-10 + 2x) + x(-5 + x)) = 56 (-10 + 2x + (-5 * x + x * x)) = 56 (-10 + 2x + (-5x + x2)) = 56 Combine like terms: 2x + -5x = -3x (-10 + -3x + x2) = 56 Solving -10 + -3x + x2 = 56 Solving for variable 'x'. Reorder the terms: -10 + -56 + -3x + x2 = 56 + -56 Combine like terms: -10 + -56 = -66 -66 + -3x + x2 = 56 + -56 Combine like terms: 56 + -56 = 0 -66 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '66' to each side of the equation. -66 + -3x + 66 + x2 = 0 + 66 Reorder the terms: -66 + 66 + -3x + x2 = 0 + 66 Combine like terms: -66 + 66 = 0 0 + -3x + x2 = 0 + 66 -3x + x2 = 0 + 66 Combine like terms: 0 + 66 = 66 -3x + x2 = 66 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 66 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 66 + 2.25 Combine like terms: 66 + 2.25 = 68.25 2.25 + -3x + x2 = 68.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 68.25 Calculate the square root of the right side: 8.261355821 Break this problem into two subproblems by setting (x + -1.5) equal to 8.261355821 and -8.261355821.Subproblem 1
x + -1.5 = 8.261355821 Simplifying x + -1.5 = 8.261355821 Reorder the terms: -1.5 + x = 8.261355821 Solving -1.5 + x = 8.261355821 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 8.261355821 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 8.261355821 + 1.5 x = 8.261355821 + 1.5 Combine like terms: 8.261355821 + 1.5 = 9.761355821 x = 9.761355821 Simplifying x = 9.761355821Subproblem 2
x + -1.5 = -8.261355821 Simplifying x + -1.5 = -8.261355821 Reorder the terms: -1.5 + x = -8.261355821 Solving -1.5 + x = -8.261355821 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -8.261355821 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -8.261355821 + 1.5 x = -8.261355821 + 1.5 Combine like terms: -8.261355821 + 1.5 = -6.761355821 x = -6.761355821 Simplifying x = -6.761355821Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.761355821, -6.761355821}
