Simplifying (x + 4)(x + -2) = 5x Reorder the terms: (4 + x)(x + -2) = 5x Reorder the terms: (4 + x)(-2 + x) = 5x Multiply (4 + x) * (-2 + x) (4(-2 + x) + x(-2 + x)) = 5x ((-2 * 4 + x * 4) + x(-2 + x)) = 5x ((-8 + 4x) + x(-2 + x)) = 5x (-8 + 4x + (-2 * x + x * x)) = 5x (-8 + 4x + (-2x + x2)) = 5x Combine like terms: 4x + -2x = 2x (-8 + 2x + x2) = 5x Solving -8 + 2x + x2 = 5x Solving for variable 'x'. Reorder the terms: -8 + 2x + -5x + x2 = 5x + -5x Combine like terms: 2x + -5x = -3x -8 + -3x + x2 = 5x + -5x Combine like terms: 5x + -5x = 0 -8 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '8' to each side of the equation. -8 + -3x + 8 + x2 = 0 + 8 Reorder the terms: -8 + 8 + -3x + x2 = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -3x + x2 = 0 + 8 -3x + x2 = 0 + 8 Combine like terms: 0 + 8 = 8 -3x + x2 = 8 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 = 8 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 8 + 2.25 Combine like terms: 8 + 2.25 = 10.25 2.25 + -3x + x2 = 10.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (x + -1.5) equal to 3.201562119 and -3.201562119.Subproblem 1
x + -1.5 = 3.201562119 Simplifying x + -1.5 = 3.201562119 Reorder the terms: -1.5 + x = 3.201562119 Solving -1.5 + x = 3.201562119 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 = 3.201562119 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 3.201562119 + 1.5 x = 3.201562119 + 1.5 Combine like terms: 3.201562119 + 1.5 = 4.701562119 x = 4.701562119 Simplifying x = 4.701562119Subproblem 2
x + -1.5 = -3.201562119 Simplifying x + -1.5 = -3.201562119 Reorder the terms: -1.5 + x = -3.201562119 Solving -1.5 + x = -3.201562119 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 = -3.201562119 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -3.201562119 + 1.5 x = -3.201562119 + 1.5 Combine like terms: -3.201562119 + 1.5 = -1.701562119 x = -1.701562119 Simplifying x = -1.701562119Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.701562119, -1.701562119}
