Simplifying x2 + 4x + -18 = 40 Reorder the terms: -18 + 4x + x2 = 40 Solving -18 + 4x + x2 = 40 Solving for variable 'x'. Reorder the terms: -18 + -40 + 4x + x2 = 40 + -40 Combine like terms: -18 + -40 = -58 -58 + 4x + x2 = 40 + -40 Combine like terms: 40 + -40 = 0 -58 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '58' to each side of the equation. -58 + 4x + 58 + x2 = 0 + 58 Reorder the terms: -58 + 58 + 4x + x2 = 0 + 58 Combine like terms: -58 + 58 = 0 0 + 4x + x2 = 0 + 58 4x + x2 = 0 + 58 Combine like terms: 0 + 58 = 58 4x + x2 = 58 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 58 + 4 Reorder the terms: 4 + 4x + x2 = 58 + 4 Combine like terms: 58 + 4 = 62 4 + 4x + x2 = 62 Factor a perfect square on the left side: (x + 2)(x + 2) = 62 Calculate the square root of the right side: 7.874007874 Break this problem into two subproblems by setting (x + 2) equal to 7.874007874 and -7.874007874.Subproblem 1
x + 2 = 7.874007874 Simplifying x + 2 = 7.874007874 Reorder the terms: 2 + x = 7.874007874 Solving 2 + x = 7.874007874 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 7.874007874 + -2 Combine like terms: 2 + -2 = 0 0 + x = 7.874007874 + -2 x = 7.874007874 + -2 Combine like terms: 7.874007874 + -2 = 5.874007874 x = 5.874007874 Simplifying x = 5.874007874Subproblem 2
x + 2 = -7.874007874 Simplifying x + 2 = -7.874007874 Reorder the terms: 2 + x = -7.874007874 Solving 2 + x = -7.874007874 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -7.874007874 + -2 Combine like terms: 2 + -2 = 0 0 + x = -7.874007874 + -2 x = -7.874007874 + -2 Combine like terms: -7.874007874 + -2 = -9.874007874 x = -9.874007874 Simplifying x = -9.874007874Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.874007874, -9.874007874}
