Simplifying x(x + 7) = 84 Reorder the terms: x(7 + x) = 84 (7 * x + x * x) = 84 (7x + x2) = 84 Solving 7x + x2 = 84 Solving for variable 'x'. Reorder the terms: -84 + 7x + x2 = 84 + -84 Combine like terms: 84 + -84 = 0 -84 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '84' to each side of the equation. -84 + 7x + 84 + x2 = 0 + 84 Reorder the terms: -84 + 84 + 7x + x2 = 0 + 84 Combine like terms: -84 + 84 = 0 0 + 7x + x2 = 0 + 84 7x + x2 = 0 + 84 Combine like terms: 0 + 84 = 84 7x + x2 = 84 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 = 84 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 84 + 12.25 Combine like terms: 84 + 12.25 = 96.25 12.25 + 7x + x2 = 96.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 96.25 Calculate the square root of the right side: 9.810708435 Break this problem into two subproblems by setting (x + 3.5) equal to 9.810708435 and -9.810708435.Subproblem 1
x + 3.5 = 9.810708435 Simplifying x + 3.5 = 9.810708435 Reorder the terms: 3.5 + x = 9.810708435 Solving 3.5 + x = 9.810708435 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 = 9.810708435 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 9.810708435 + -3.5 x = 9.810708435 + -3.5 Combine like terms: 9.810708435 + -3.5 = 6.310708435 x = 6.310708435 Simplifying x = 6.310708435Subproblem 2
x + 3.5 = -9.810708435 Simplifying x + 3.5 = -9.810708435 Reorder the terms: 3.5 + x = -9.810708435 Solving 3.5 + x = -9.810708435 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 = -9.810708435 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -9.810708435 + -3.5 x = -9.810708435 + -3.5 Combine like terms: -9.810708435 + -3.5 = -13.310708435 x = -13.310708435 Simplifying x = -13.310708435Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.310708435, -13.310708435}
