Simplifying x(x + 7) = 2160000 Reorder the terms: x(7 + x) = 2160000 (7 * x + x * x) = 2160000 (7x + x2) = 2160000 Solving 7x + x2 = 2160000 Solving for variable 'x'. Reorder the terms: -2160000 + 7x + x2 = 2160000 + -2160000 Combine like terms: 2160000 + -2160000 = 0 -2160000 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2160000' to each side of the equation. -2160000 + 7x + 2160000 + x2 = 0 + 2160000 Reorder the terms: -2160000 + 2160000 + 7x + x2 = 0 + 2160000 Combine like terms: -2160000 + 2160000 = 0 0 + 7x + x2 = 0 + 2160000 7x + x2 = 0 + 2160000 Combine like terms: 0 + 2160000 = 2160000 7x + x2 = 2160000 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 2160000 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 2160000 + 12.25 Combine like terms: 2160000 + 12.25 = 2160012.25 12.25 + 7x + x2 = 2160012.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 2160012.25 Calculate the square root of the right side: 1469.698013199 Break this problem into two subproblems by setting (x + 3.5) equal to 1469.698013199 and -1469.698013199.Subproblem 1
x + 3.5 = 1469.698013199 Simplifying x + 3.5 = 1469.698013199 Reorder the terms: 3.5 + x = 1469.698013199 Solving 3.5 + x = 1469.698013199 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 1469.698013199 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 1469.698013199 + -3.5 x = 1469.698013199 + -3.5 Combine like terms: 1469.698013199 + -3.5 = 1466.198013199 x = 1466.198013199 Simplifying x = 1466.198013199Subproblem 2
x + 3.5 = -1469.698013199 Simplifying x + 3.5 = -1469.698013199 Reorder the terms: 3.5 + x = -1469.698013199 Solving 3.5 + x = -1469.698013199 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -1469.698013199 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -1469.698013199 + -3.5 x = -1469.698013199 + -3.5 Combine like terms: -1469.698013199 + -3.5 = -1473.198013199 x = -1473.198013199 Simplifying x = -1473.198013199Solution
The solution to the problem is based on the solutions from the subproblems. x = {1466.198013199, -1473.198013199}
