Simplifying 4(x + -2) + 9 = 2x(-1 + x) Reorder the terms: 4(-2 + x) + 9 = 2x(-1 + x) (-2 * 4 + x * 4) + 9 = 2x(-1 + x) (-8 + 4x) + 9 = 2x(-1 + x) Reorder the terms: -8 + 9 + 4x = 2x(-1 + x) Combine like terms: -8 + 9 = 1 1 + 4x = 2x(-1 + x) 1 + 4x = (-1 * 2x + x * 2x) 1 + 4x = (-2x + 2x2) Solving 1 + 4x = -2x + 2x2 Solving for variable 'x'. Combine like terms: 4x + 2x = 6x 1 + 6x + -2x2 = -2x + 2x2 + 2x + -2x2 Reorder the terms: 1 + 6x + -2x2 = -2x + 2x + 2x2 + -2x2 Combine like terms: -2x + 2x = 0 1 + 6x + -2x2 = 0 + 2x2 + -2x2 1 + 6x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 1 + 6x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -0.5 + -3x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -3x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -3x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -3x + x2 = 0 + 0.5 -3x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -3x + x2 = 0.5 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 = 0.5 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 0.5 + 2.25 Combine like terms: 0.5 + 2.25 = 2.75 2.25 + -3x + x2 = 2.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 2.75 Calculate the square root of the right side: 1.658312395 Break this problem into two subproblems by setting (x + -1.5) equal to 1.658312395 and -1.658312395.Subproblem 1
x + -1.5 = 1.658312395 Simplifying x + -1.5 = 1.658312395 Reorder the terms: -1.5 + x = 1.658312395 Solving -1.5 + x = 1.658312395 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 = 1.658312395 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 1.658312395 + 1.5 x = 1.658312395 + 1.5 Combine like terms: 1.658312395 + 1.5 = 3.158312395 x = 3.158312395 Simplifying x = 3.158312395Subproblem 2
x + -1.5 = -1.658312395 Simplifying x + -1.5 = -1.658312395 Reorder the terms: -1.5 + x = -1.658312395 Solving -1.5 + x = -1.658312395 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 = -1.658312395 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -1.658312395 + 1.5 x = -1.658312395 + 1.5 Combine like terms: -1.658312395 + 1.5 = -0.158312395 x = -0.158312395 Simplifying x = -0.158312395Solution
