Simplifying (2x + 20)(x + 30) = 825 Reorder the terms: (20 + 2x)(x + 30) = 825 Reorder the terms: (20 + 2x)(30 + x) = 825 Multiply (20 + 2x) * (30 + x) (20(30 + x) + 2x * (30 + x)) = 825 ((30 * 20 + x * 20) + 2x * (30 + x)) = 825 ((600 + 20x) + 2x * (30 + x)) = 825 (600 + 20x + (30 * 2x + x * 2x)) = 825 (600 + 20x + (60x + 2x2)) = 825 Combine like terms: 20x + 60x = 80x (600 + 80x + 2x2) = 825 Solving 600 + 80x + 2x2 = 825 Solving for variable 'x'. Reorder the terms: 600 + -825 + 80x + 2x2 = 825 + -825 Combine like terms: 600 + -825 = -225 -225 + 80x + 2x2 = 825 + -825 Combine like terms: 825 + -825 = 0 -225 + 80x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -112.5 + 40x + x2 = 0 Move the constant term to the right: Add '112.5' to each side of the equation. -112.5 + 40x + 112.5 + x2 = 0 + 112.5 Reorder the terms: -112.5 + 112.5 + 40x + x2 = 0 + 112.5 Combine like terms: -112.5 + 112.5 = 0.0 0.0 + 40x + x2 = 0 + 112.5 40x + x2 = 0 + 112.5 Combine like terms: 0 + 112.5 = 112.5 40x + x2 = 112.5 The x term is 40x. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40x + 400 + x2 = 112.5 + 400 Reorder the terms: 400 + 40x + x2 = 112.5 + 400 Combine like terms: 112.5 + 400 = 512.5 400 + 40x + x2 = 512.5 Factor a perfect square on the left side: (x + 20)(x + 20) = 512.5 Calculate the square root of the right side: 22.638462845 Break this problem into two subproblems by setting (x + 20) equal to 22.638462845 and -22.638462845.Subproblem 1
x + 20 = 22.638462845 Simplifying x + 20 = 22.638462845 Reorder the terms: 20 + x = 22.638462845 Solving 20 + x = 22.638462845 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = 22.638462845 + -20 Combine like terms: 20 + -20 = 0 0 + x = 22.638462845 + -20 x = 22.638462845 + -20 Combine like terms: 22.638462845 + -20 = 2.638462845 x = 2.638462845 Simplifying x = 2.638462845Subproblem 2
x + 20 = -22.638462845 Simplifying x + 20 = -22.638462845 Reorder the terms: 20 + x = -22.638462845 Solving 20 + x = -22.638462845 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = -22.638462845 + -20 Combine like terms: 20 + -20 = 0 0 + x = -22.638462845 + -20 x = -22.638462845 + -20 Combine like terms: -22.638462845 + -20 = -42.638462845 x = -42.638462845 Simplifying x = -42.638462845Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.638462845, -42.638462845}
