Simplifying x(x + -15) = 2 Reorder the terms: x(-15 + x) = 2 (-15 * x + x * x) = 2 (-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 = 15.132168761 x = 15.132168761 Simplifying x = 15.132168761Subproblem 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 = -0.132168761 x = -0.132168761 Simplifying x = -0.132168761Solution
The solution to the problem is based on the solutions from the subproblems. x = {15.132168761, -0.132168761}
