Simplifying (x + -4)(x + 2) = 12 Reorder the terms: (-4 + x)(x + 2) = 12 Reorder the terms: (-4 + x)(2 + x) = 12 Multiply (-4 + x) * (2 + x) (-4(2 + x) + x(2 + x)) = 12 ((2 * -4 + x * -4) + x(2 + x)) = 12 ((-8 + -4x) + x(2 + x)) = 12 (-8 + -4x + (2 * x + x * x)) = 12 (-8 + -4x + (2x + x2)) = 12 Combine like terms: -4x + 2x = -2x (-8 + -2x + x2) = 12 Solving -8 + -2x + x2 = 12 Solving for variable 'x'. Reorder the terms: -8 + -12 + -2x + x2 = 12 + -12 Combine like terms: -8 + -12 = -20 -20 + -2x + x2 = 12 + -12 Combine like terms: 12 + -12 = 0 -20 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + -2x + 20 + x2 = 0 + 20 Reorder the terms: -20 + 20 + -2x + x2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -2x + x2 = 0 + 20 -2x + x2 = 0 + 20 Combine like terms: 0 + 20 = 20 -2x + x2 = 20 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 20 + 1 Reorder the terms: 1 + -2x + x2 = 20 + 1 Combine like terms: 20 + 1 = 21 1 + -2x + x2 = 21 Factor a perfect square on the left side: (x + -1)(x + -1) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x + -1) equal to 4.582575695 and -4.582575695.Subproblem 1
x + -1 = 4.582575695 Simplifying x + -1 = 4.582575695 Reorder the terms: -1 + x = 4.582575695 Solving -1 + x = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + x = 4.582575695 + 1 x = 4.582575695 + 1 Combine like terms: 4.582575695 + 1 = 5.582575695 x = 5.582575695 Simplifying x = 5.582575695Subproblem 2
x + -1 = -4.582575695 Simplifying x + -1 = -4.582575695 Reorder the terms: -1 + x = -4.582575695 Solving -1 + x = -4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -4.582575695 + 1 Combine like terms: -1 + 1 = 0 0 + x = -4.582575695 + 1 x = -4.582575695 + 1 Combine like terms: -4.582575695 + 1 = -3.582575695 x = -3.582575695 Simplifying x = -3.582575695Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.582575695, -3.582575695}
