Simplifying x2 + 15x = 2 Reorder the terms: 15x + x2 = 2 Solving 15x + x2 = 2 Solving for variable 'x'. Reorder the terms: -2 + 15x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 -2 + 15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 15x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 15x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 15x + x2 = 0 + 2 15x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 15x + x2 = 2 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 = 2 + 56.25 Reorder the terms: 56.25 + 15x + x2 = 2 + 56.25 Combine like terms: 2 + 56.25 = 58.25 56.25 + 15x + x2 = 58.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 58.25 Calculate the square root of the right side: 7.632168761 Break this problem into two subproblems by setting (x + 7.5) equal to 7.632168761 and -7.632168761.Subproblem 1
x + 7.5 = 7.632168761 Simplifying x + 7.5 = 7.632168761 Reorder the terms: 7.5 + x = 7.632168761 Solving 7.5 + x = 7.632168761 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 = 7.632168761 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 7.632168761 + -7.5 x = 7.632168761 + -7.5 Combine like terms: 7.632168761 + -7.5 = 0.132168761 x = 0.132168761 Simplifying x = 0.132168761Subproblem 2
x + 7.5 = -7.632168761 Simplifying x + 7.5 = -7.632168761 Reorder the terms: 7.5 + x = -7.632168761 Solving 7.5 + x = -7.632168761 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 = -7.632168761 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -7.632168761 + -7.5 x = -7.632168761 + -7.5 Combine like terms: -7.632168761 + -7.5 = -15.132168761 x = -15.132168761 Simplifying x = -15.132168761Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.132168761, -15.132168761}
