Simplifying (2x + 9)(4x + -3) = 8x + -12 Reorder the terms: (9 + 2x)(4x + -3) = 8x + -12 Reorder the terms: (9 + 2x)(-3 + 4x) = 8x + -12 Multiply (9 + 2x) * (-3 + 4x) (9(-3 + 4x) + 2x * (-3 + 4x)) = 8x + -12 ((-3 * 9 + 4x * 9) + 2x * (-3 + 4x)) = 8x + -12 ((-27 + 36x) + 2x * (-3 + 4x)) = 8x + -12 (-27 + 36x + (-3 * 2x + 4x * 2x)) = 8x + -12 (-27 + 36x + (-6x + 8x2)) = 8x + -12 Combine like terms: 36x + -6x = 30x (-27 + 30x + 8x2) = 8x + -12 Reorder the terms: -27 + 30x + 8x2 = -12 + 8x Solving -27 + 30x + 8x2 = -12 + 8x Solving for variable 'x'. Reorder the terms: -27 + 12 + 30x + -8x + 8x2 = -12 + 8x + 12 + -8x Combine like terms: -27 + 12 = -15 -15 + 30x + -8x + 8x2 = -12 + 8x + 12 + -8x Combine like terms: 30x + -8x = 22x -15 + 22x + 8x2 = -12 + 8x + 12 + -8x Reorder the terms: -15 + 22x + 8x2 = -12 + 12 + 8x + -8x Combine like terms: -12 + 12 = 0 -15 + 22x + 8x2 = 0 + 8x + -8x -15 + 22x + 8x2 = 8x + -8x Combine like terms: 8x + -8x = 0 -15 + 22x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -1.875 + 2.75x + x2 = 0 Move the constant term to the right: Add '1.875' to each side of the equation. -1.875 + 2.75x + 1.875 + x2 = 0 + 1.875 Reorder the terms: -1.875 + 1.875 + 2.75x + x2 = 0 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + 2.75x + x2 = 0 + 1.875 2.75x + x2 = 0 + 1.875 Combine like terms: 0 + 1.875 = 1.875 2.75x + x2 = 1.875 The x term is 2.75x. Take half its coefficient (1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. 2.75x + 1.890625 + x2 = 1.875 + 1.890625 Reorder the terms: 1.890625 + 2.75x + x2 = 1.875 + 1.890625 Combine like terms: 1.875 + 1.890625 = 3.765625 1.890625 + 2.75x + x2 = 3.765625 Factor a perfect square on the left side: (x + 1.375)(x + 1.375) = 3.765625 Calculate the square root of the right side: 1.940521837 Break this problem into two subproblems by setting (x + 1.375) equal to 1.940521837 and -1.940521837.Subproblem 1
x + 1.375 = 1.940521837 Simplifying x + 1.375 = 1.940521837 Reorder the terms: 1.375 + x = 1.940521837 Solving 1.375 + x = 1.940521837 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.375' to each side of the equation. 1.375 + -1.375 + x = 1.940521837 + -1.375 Combine like terms: 1.375 + -1.375 = 0.000 0.000 + x = 1.940521837 + -1.375 x = 1.940521837 + -1.375 Combine like terms: 1.940521837 + -1.375 = 0.565521837 x = 0.565521837 Simplifying x = 0.565521837Subproblem 2
x + 1.375 = -1.940521837 Simplifying x + 1.375 = -1.940521837 Reorder the terms: 1.375 + x = -1.940521837 Solving 1.375 + x = -1.940521837 Solving for variable 'x'.
