Simplifying (x + 4)(x + -12) = -5x Reorder the terms: (4 + x)(x + -12) = -5x Reorder the terms: (4 + x)(-12 + x) = -5x Multiply (4 + x) * (-12 + x) (4(-12 + x) + x(-12 + x)) = -5x ((-12 * 4 + x * 4) + x(-12 + x)) = -5x ((-48 + 4x) + x(-12 + x)) = -5x (-48 + 4x + (-12 * x + x * x)) = -5x (-48 + 4x + (-12x + x2)) = -5x Combine like terms: 4x + -12x = -8x (-48 + -8x + x2) = -5x Solving -48 + -8x + x2 = -5x Solving for variable 'x'. Reorder the terms: -48 + -8x + 5x + x2 = -5x + 5x Combine like terms: -8x + 5x = -3x -48 + -3x + x2 = -5x + 5x Combine like terms: -5x + 5x = 0 -48 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '48' to each side of the equation. -48 + -3x + 48 + x2 = 0 + 48 Reorder the terms: -48 + 48 + -3x + x2 = 0 + 48 Combine like terms: -48 + 48 = 0 0 + -3x + x2 = 0 + 48 -3x + x2 = 0 + 48 Combine like terms: 0 + 48 = 48 -3x + x2 = 48 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 = 48 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 48 + 2.25 Combine like terms: 48 + 2.25 = 50.25 2.25 + -3x + x2 = 50.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 50.25 Calculate the square root of the right side: 7.088723439 Break this problem into two subproblems by setting (x + -1.5) equal to 7.088723439 and -7.088723439.Subproblem 1
x + -1.5 = 7.088723439 Simplifying x + -1.5 = 7.088723439 Reorder the terms: -1.5 + x = 7.088723439 Solving -1.5 + x = 7.088723439 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 = 7.088723439 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 7.088723439 + 1.5 x = 7.088723439 + 1.5 Combine like terms: 7.088723439 + 1.5 = 8.588723439 x = 8.588723439 Simplifying x = 8.588723439Subproblem 2
x + -1.5 = -7.088723439 Simplifying x + -1.5 = -7.088723439 Reorder the terms: -1.5 + x = -7.088723439 Solving -1.5 + x = -7.088723439 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 = -7.088723439 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -7.088723439 + 1.5 x = -7.088723439 + 1.5 Combine like terms: -7.088723439 + 1.5 = -5.588723439 x = -5.588723439 Simplifying x = -5.588723439Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.588723439, -5.588723439}
