Simplifying x * x + 7x = 4 * 4 + 8 * 4 Multiply x * x x2 + 7x = 4 * 4 + 8 * 4 Reorder the terms: 7x + x2 = 4 * 4 + 8 * 4 Multiply 4 * 4 7x + x2 = 16 + 8 * 4 Multiply 8 * 4 7x + x2 = 16 + 32 Combine like terms: 16 + 32 = 48 7x + x2 = 48 Solving 7x + x2 = 48 Solving for variable 'x'. Reorder the terms: -48 + 7x + x2 = 48 + -48 Combine like terms: 48 + -48 = 0 -48 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '48' to each side of the equation. -48 + 7x + 48 + x2 = 0 + 48 Reorder the terms: -48 + 48 + 7x + x2 = 0 + 48 Combine like terms: -48 + 48 = 0 0 + 7x + x2 = 0 + 48 7x + x2 = 0 + 48 Combine like terms: 0 + 48 = 48 7x + x2 = 48 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 = 48 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 48 + 12.25 Combine like terms: 48 + 12.25 = 60.25 12.25 + 7x + x2 = 60.25 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 60.25 Calculate the square root of the right side: 7.762087348 Break this problem into two subproblems by setting (x + 3.5) equal to 7.762087348 and -7.762087348.Subproblem 1
x + 3.5 = 7.762087348 Simplifying x + 3.5 = 7.762087348 Reorder the terms: 3.5 + x = 7.762087348 Solving 3.5 + x = 7.762087348 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 = 7.762087348 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 7.762087348 + -3.5 x = 7.762087348 + -3.5 Combine like terms: 7.762087348 + -3.5 = 4.262087348 x = 4.262087348 Simplifying x = 4.262087348Subproblem 2
x + 3.5 = -7.762087348 Simplifying x + 3.5 = -7.762087348 Reorder the terms: 3.5 + x = -7.762087348 Solving 3.5 + x = -7.762087348 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 = -7.762087348 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -7.762087348 + -3.5 x = -7.762087348 + -3.5 Combine like terms: -7.762087348 + -3.5 = -11.262087348 x = -11.262087348 Simplifying x = -11.262087348Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.262087348, -11.262087348}
