Simplifying (4x + 9)(x + -4) + -8x + 18 = 0 Reorder the terms: (9 + 4x)(x + -4) + -8x + 18 = 0 Reorder the terms: (9 + 4x)(-4 + x) + -8x + 18 = 0 Multiply (9 + 4x) * (-4 + x) (9(-4 + x) + 4x * (-4 + x)) + -8x + 18 = 0 ((-4 * 9 + x * 9) + 4x * (-4 + x)) + -8x + 18 = 0 ((-36 + 9x) + 4x * (-4 + x)) + -8x + 18 = 0 (-36 + 9x + (-4 * 4x + x * 4x)) + -8x + 18 = 0 (-36 + 9x + (-16x + 4x2)) + -8x + 18 = 0 Combine like terms: 9x + -16x = -7x (-36 + -7x + 4x2) + -8x + 18 = 0 Reorder the terms: -36 + 18 + -7x + -8x + 4x2 = 0 Combine like terms: -36 + 18 = -18 -18 + -7x + -8x + 4x2 = 0 Combine like terms: -7x + -8x = -15x -18 + -15x + 4x2 = 0 Solving -18 + -15x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -4.5 + -3.75x + x2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + -3.75x + 4.5 + x2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + -3.75x + x2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + -3.75x + x2 = 0 + 4.5 -3.75x + x2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 -3.75x + x2 = 4.5 The x term is -3.75x. Take half its coefficient (-1.875). Square it (3.515625) and add it to both sides. Add '3.515625' to each side of the equation. -3.75x + 3.515625 + x2 = 4.5 + 3.515625 Reorder the terms: 3.515625 + -3.75x + x2 = 4.5 + 3.515625 Combine like terms: 4.5 + 3.515625 = 8.015625 3.515625 + -3.75x + x2 = 8.015625 Factor a perfect square on the left side: (x + -1.875)(x + -1.875) = 8.015625 Calculate the square root of the right side: 2.831187913 Break this problem into two subproblems by setting (x + -1.875) equal to 2.831187913 and -2.831187913.Subproblem 1
x + -1.875 = 2.831187913 Simplifying x + -1.875 = 2.831187913 Reorder the terms: -1.875 + x = 2.831187913 Solving -1.875 + x = 2.831187913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.875' to each side of the equation. -1.875 + 1.875 + x = 2.831187913 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + x = 2.831187913 + 1.875 x = 2.831187913 + 1.875 Combine like terms: 2.831187913 + 1.875 = 4.706187913 x = 4.706187913 Simplifying x = 4.706187913Subproblem 2
x + -1.875 = -2.831187913 Simplifying x + -1.875 = -2.831187913 Reorder the terms: -1.875 + x = -2.831187913 Solving -1.875 + x = -2.831187913 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.875' to each side of the equation. -1.875 + 1.875 + x = -2.831187913 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + x = -2.831187913 + 1.875 x = -2.831187913 + 1.875 Combine like terms: -2.831187913 + 1.875 = -0.956187913 x = -0.956187913 Simplifying x = -0.956187913Solution
