Simplifying (8x + -1)(5 + 2x) = (4x + -5) * 2 Reorder the terms: (-1 + 8x)(5 + 2x) = (4x + -5) * 2 Multiply (-1 + 8x) * (5 + 2x) (-1(5 + 2x) + 8x * (5 + 2x)) = (4x + -5) * 2 ((5 * -1 + 2x * -1) + 8x * (5 + 2x)) = (4x + -5) * 2 ((-5 + -2x) + 8x * (5 + 2x)) = (4x + -5) * 2 (-5 + -2x + (5 * 8x + 2x * 8x)) = (4x + -5) * 2 (-5 + -2x + (40x + 16x2)) = (4x + -5) * 2 Combine like terms: -2x + 40x = 38x (-5 + 38x + 16x2) = (4x + -5) * 2 Reorder the terms: -5 + 38x + 16x2 = (-5 + 4x) * 2 Reorder the terms for easier multiplication: -5 + 38x + 16x2 = 2(-5 + 4x) -5 + 38x + 16x2 = (-5 * 2 + 4x * 2) -5 + 38x + 16x2 = (-10 + 8x) Solving -5 + 38x + 16x2 = -10 + 8x Solving for variable 'x'. Reorder the terms: -5 + 10 + 38x + -8x + 16x2 = -10 + 8x + 10 + -8x Combine like terms: -5 + 10 = 5 5 + 38x + -8x + 16x2 = -10 + 8x + 10 + -8x Combine like terms: 38x + -8x = 30x 5 + 30x + 16x2 = -10 + 8x + 10 + -8x Reorder the terms: 5 + 30x + 16x2 = -10 + 10 + 8x + -8x Combine like terms: -10 + 10 = 0 5 + 30x + 16x2 = 0 + 8x + -8x 5 + 30x + 16x2 = 8x + -8x Combine like terms: 8x + -8x = 0 5 + 30x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 0.3125 + 1.875x + x2 = 0 Move the constant term to the right: Add '-0.3125' to each side of the equation. 0.3125 + 1.875x + -0.3125 + x2 = 0 + -0.3125 Reorder the terms: 0.3125 + -0.3125 + 1.875x + x2 = 0 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + 1.875x + x2 = 0 + -0.3125 1.875x + x2 = 0 + -0.3125 Combine like terms: 0 + -0.3125 = -0.3125 1.875x + x2 = -0.3125 The x term is 1.875x. Take half its coefficient (0.9375). Square it (0.87890625) and add it to both sides. Add '0.87890625' to each side of the equation. 1.875x + 0.87890625 + x2 = -0.3125 + 0.87890625 Reorder the terms: 0.87890625 + 1.875x + x2 = -0.3125 + 0.87890625 Combine like terms: -0.3125 + 0.87890625 = 0.56640625 0.87890625 + 1.875x + x2 = 0.56640625 Factor a perfect square on the left side: (x + 0.9375)(x + 0.9375) = 0.56640625 Calculate the square root of the right side: 0.752599661 Break this problem into two subproblems by setting (x + 0.9375) equal to 0.752599661 and -0.752599661.Subproblem 1
