Simplifying (2x + 1)(x + 15) = x Reorder the terms: (1 + 2x)(x + 15) = x Reorder the terms: (1 + 2x)(15 + x) = x Multiply (1 + 2x) * (15 + x) (1(15 + x) + 2x * (15 + x)) = x ((15 * 1 + x * 1) + 2x * (15 + x)) = x ((15 + 1x) + 2x * (15 + x)) = x (15 + 1x + (15 * 2x + x * 2x)) = x (15 + 1x + (30x + 2x2)) = x Combine like terms: 1x + 30x = 31x (15 + 31x + 2x2) = x Solving 15 + 31x + 2x2 = x Solving for variable 'x'. Reorder the terms: 15 + 31x + -1x + 2x2 = x + -1x Combine like terms: 31x + -1x = 30x 15 + 30x + 2x2 = x + -1x Combine like terms: x + -1x = 0 15 + 30x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7.5 + 15x + x2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + 15x + -7.5 + x2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + 15x + x2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + 15x + x2 = 0 + -7.5 15x + x2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 15x + x2 = -7.5 The x term is 15x. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15x + 56.25 + x2 = -7.5 + 56.25 Reorder the terms: 56.25 + 15x + x2 = -7.5 + 56.25 Combine like terms: -7.5 + 56.25 = 48.75 56.25 + 15x + x2 = 48.75 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 48.75 Calculate the square root of the right side: 6.982120022 Break this problem into two subproblems by setting (x + 7.5) equal to 6.982120022 and -6.982120022.Subproblem 1
x + 7.5 = 6.982120022 Simplifying x + 7.5 = 6.982120022 Reorder the terms: 7.5 + x = 6.982120022 Solving 7.5 + x = 6.982120022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = 6.982120022 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 6.982120022 + -7.5 x = 6.982120022 + -7.5 Combine like terms: 6.982120022 + -7.5 = -0.517879978 x = -0.517879978 Simplifying x = -0.517879978Subproblem 2
x + 7.5 = -6.982120022 Simplifying x + 7.5 = -6.982120022 Reorder the terms: 7.5 + x = -6.982120022 Solving 7.5 + x = -6.982120022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = -6.982120022 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -6.982120022 + -7.5 x = -6.982120022 + -7.5 Combine like terms: -6.982120022 + -7.5 = -14.482120022 x = -14.482120022 Simplifying x = -14.482120022Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.517879978, -14.482120022}
