Simplifying (10 + -2x)(8 + -2x) = 38.75 Multiply (10 + -2x) * (8 + -2x) (10(8 + -2x) + -2x * (8 + -2x)) = 38.75 ((8 * 10 + -2x * 10) + -2x * (8 + -2x)) = 38.75 ((80 + -20x) + -2x * (8 + -2x)) = 38.75 (80 + -20x + (8 * -2x + -2x * -2x)) = 38.75 (80 + -20x + (-16x + 4x2)) = 38.75 Combine like terms: -20x + -16x = -36x (80 + -36x + 4x2) = 38.75 Solving 80 + -36x + 4x2 = 38.75 Solving for variable 'x'. Reorder the terms: 80 + -38.75 + -36x + 4x2 = 38.75 + -38.75 Combine like terms: 80 + -38.75 = 41.25 41.25 + -36x + 4x2 = 38.75 + -38.75 Combine like terms: 38.75 + -38.75 = 0.00 41.25 + -36x + 4x2 = 0.00 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 10.3125 + -9x + x2 = 0.00 Move the constant term to the right: Add '-10.3125' to each side of the equation. 10.3125 + -9x + -10.3125 + x2 = 0.00 + -10.3125 Reorder the terms: 10.3125 + -10.3125 + -9x + x2 = 0.00 + -10.3125 Combine like terms: 10.3125 + -10.3125 = 0.0000 0.0000 + -9x + x2 = 0.00 + -10.3125 -9x + x2 = 0.00 + -10.3125 Combine like terms: 0.00 + -10.3125 = -10.3125 -9x + x2 = -10.3125 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = -10.3125 + 20.25 Reorder the terms: 20.25 + -9x + x2 = -10.3125 + 20.25 Combine like terms: -10.3125 + 20.25 = 9.9375 20.25 + -9x + x2 = 9.9375 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 9.9375 Calculate the square root of the right side: 3.152380053 Break this problem into two subproblems by setting (x + -4.5) equal to 3.152380053 and -3.152380053.Subproblem 1
x + -4.5 = 3.152380053 Simplifying x + -4.5 = 3.152380053 Reorder the terms: -4.5 + x = 3.152380053 Solving -4.5 + x = 3.152380053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 3.152380053 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 3.152380053 + 4.5 x = 3.152380053 + 4.5 Combine like terms: 3.152380053 + 4.5 = 7.652380053 x = 7.652380053 Simplifying x = 7.652380053Subproblem 2
