Simplifying x2 + -15x = 4 Reorder the terms: -15x + x2 = 4 Solving -15x + x2 = 4 Solving for variable 'x'. Reorder the terms: -4 + -15x + x2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + -15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + -15x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + -15x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -15x + x2 = 0 + 4 -15x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 -15x + x2 = 4 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 = 4 + 56.25 Reorder the terms: 56.25 + -15x + x2 = 4 + 56.25 Combine like terms: 4 + 56.25 = 60.25 56.25 + -15x + x2 = 60.25 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 60.25 Calculate the square root of the right side: 7.762087348 Break this problem into two subproblems by setting (x + -7.5) equal to 7.762087348 and -7.762087348.Subproblem 1
x + -7.5 = 7.762087348 Simplifying x + -7.5 = 7.762087348 Reorder the terms: -7.5 + x = 7.762087348 Solving -7.5 + x = 7.762087348 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 = 7.762087348 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = 7.762087348 + 7.5 x = 7.762087348 + 7.5 Combine like terms: 7.762087348 + 7.5 = 15.262087348 x = 15.262087348 Simplifying x = 15.262087348Subproblem 2
x + -7.5 = -7.762087348 Simplifying x + -7.5 = -7.762087348 Reorder the terms: -7.5 + x = -7.762087348 Solving -7.5 + x = -7.762087348 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 = -7.762087348 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + x = -7.762087348 + 7.5 x = -7.762087348 + 7.5 Combine like terms: -7.762087348 + 7.5 = -0.262087348 x = -0.262087348 Simplifying x = -0.262087348Solution
The solution to the problem is based on the solutions from the subproblems. x = {15.262087348, -0.262087348}
