Simplifying x(x + 8) = 72 Reorder the terms: x(8 + x) = 72 (8 * x + x * x) = 72 (8x + x2) = 72 Solving 8x + x2 = 72 Solving for variable 'x'. Reorder the terms: -72 + 8x + x2 = 72 + -72 Combine like terms: 72 + -72 = 0 -72 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '72' to each side of the equation. -72 + 8x + 72 + x2 = 0 + 72 Reorder the terms: -72 + 72 + 8x + x2 = 0 + 72 Combine like terms: -72 + 72 = 0 0 + 8x + x2 = 0 + 72 8x + x2 = 0 + 72 Combine like terms: 0 + 72 = 72 8x + x2 = 72 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 72 + 16 Reorder the terms: 16 + 8x + x2 = 72 + 16 Combine like terms: 72 + 16 = 88 16 + 8x + x2 = 88 Factor a perfect square on the left side: (x + 4)(x + 4) = 88 Calculate the square root of the right side: 9.38083152 Break this problem into two subproblems by setting (x + 4) equal to 9.38083152 and -9.38083152.Subproblem 1
x + 4 = 9.38083152 Simplifying x + 4 = 9.38083152 Reorder the terms: 4 + x = 9.38083152 Solving 4 + x = 9.38083152 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 9.38083152 + -4 Combine like terms: 4 + -4 = 0 0 + x = 9.38083152 + -4 x = 9.38083152 + -4 Combine like terms: 9.38083152 + -4 = 5.38083152 x = 5.38083152 Simplifying x = 5.38083152Subproblem 2
x + 4 = -9.38083152 Simplifying x + 4 = -9.38083152 Reorder the terms: 4 + x = -9.38083152 Solving 4 + x = -9.38083152 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -9.38083152 + -4 Combine like terms: 4 + -4 = 0 0 + x = -9.38083152 + -4 x = -9.38083152 + -4 Combine like terms: -9.38083152 + -4 = -13.38083152 x = -13.38083152 Simplifying x = -13.38083152Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.38083152, -13.38083152}
