Simplifying (2x + -2)(2x + -8) = 9 Reorder the terms: (-2 + 2x)(2x + -8) = 9 Reorder the terms: (-2 + 2x)(-8 + 2x) = 9 Multiply (-2 + 2x) * (-8 + 2x) (-2(-8 + 2x) + 2x * (-8 + 2x)) = 9 ((-8 * -2 + 2x * -2) + 2x * (-8 + 2x)) = 9 ((16 + -4x) + 2x * (-8 + 2x)) = 9 (16 + -4x + (-8 * 2x + 2x * 2x)) = 9 (16 + -4x + (-16x + 4x2)) = 9 Combine like terms: -4x + -16x = -20x (16 + -20x + 4x2) = 9 Solving 16 + -20x + 4x2 = 9 Solving for variable 'x'. Reorder the terms: 16 + -9 + -20x + 4x2 = 9 + -9 Combine like terms: 16 + -9 = 7 7 + -20x + 4x2 = 9 + -9 Combine like terms: 9 + -9 = 0 7 + -20x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.75 + -5x + x2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -5x + -1.75 + x2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -5x + x2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -5x + x2 = 0 + -1.75 -5x + x2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -5x + x2 = -1.75 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -1.75 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -1.75 + 6.25 Combine like terms: -1.75 + 6.25 = 4.5 6.25 + -5x + x2 = 4.5 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 4.5 Calculate the square root of the right side: 2.121320344 Break this problem into two subproblems by setting (x + -2.5) equal to 2.121320344 and -2.121320344.Subproblem 1
x + -2.5 = 2.121320344 Simplifying x + -2.5 = 2.121320344 Reorder the terms: -2.5 + x = 2.121320344 Solving -2.5 + x = 2.121320344 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 2.121320344 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 2.121320344 + 2.5 x = 2.121320344 + 2.5 Combine like terms: 2.121320344 + 2.5 = 4.621320344 x = 4.621320344 Simplifying x = 4.621320344Subproblem 2
x + -2.5 = -2.121320344 Simplifying x + -2.5 = -2.121320344 Reorder the terms: -2.5 + x = -2.121320344 Solving -2.5 + x = -2.121320344 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -2.121320344 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -2.121320344 + 2.5 x = -2.121320344 + 2.5 Combine like terms: -2.121320344 + 2.5 = 0.378679656 x = 0.378679656 Simplifying x = 0.378679656Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.621320344, 0.378679656}
