Simplifying (x2) + 40x + 40 = 4x + 4 x2 + 40x + 40 = 4x + 4 Reorder the terms: 40 + 40x + x2 = 4x + 4 Reorder the terms: 40 + 40x + x2 = 4 + 4x Solving 40 + 40x + x2 = 4 + 4x Solving for variable 'x'. Reorder the terms: 40 + -4 + 40x + -4x + x2 = 4 + 4x + -4 + -4x Combine like terms: 40 + -4 = 36 36 + 40x + -4x + x2 = 4 + 4x + -4 + -4x Combine like terms: 40x + -4x = 36x 36 + 36x + x2 = 4 + 4x + -4 + -4x Reorder the terms: 36 + 36x + x2 = 4 + -4 + 4x + -4x Combine like terms: 4 + -4 = 0 36 + 36x + x2 = 0 + 4x + -4x 36 + 36x + x2 = 4x + -4x Combine like terms: 4x + -4x = 0 36 + 36x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-36' to each side of the equation. 36 + 36x + -36 + x2 = 0 + -36 Reorder the terms: 36 + -36 + 36x + x2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + 36x + x2 = 0 + -36 36x + x2 = 0 + -36 Combine like terms: 0 + -36 = -36 36x + x2 = -36 The x term is 36x. Take half its coefficient (18). Square it (324) and add it to both sides. Add '324' to each side of the equation. 36x + 324 + x2 = -36 + 324 Reorder the terms: 324 + 36x + x2 = -36 + 324 Combine like terms: -36 + 324 = 288 324 + 36x + x2 = 288 Factor a perfect square on the left side: (x + 18)(x + 18) = 288 Calculate the square root of the right side: 16.970562748 Break this problem into two subproblems by setting (x + 18) equal to 16.970562748 and -16.970562748.Subproblem 1
x + 18 = 16.970562748 Simplifying x + 18 = 16.970562748 Reorder the terms: 18 + x = 16.970562748 Solving 18 + x = 16.970562748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + x = 16.970562748 + -18 Combine like terms: 18 + -18 = 0 0 + x = 16.970562748 + -18 x = 16.970562748 + -18 Combine like terms: 16.970562748 + -18 = -1.029437252 x = -1.029437252 Simplifying x = -1.029437252Subproblem 2
x + 18 = -16.970562748 Simplifying x + 18 = -16.970562748 Reorder the terms: 18 + x = -16.970562748 Solving 18 + x = -16.970562748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + x = -16.970562748 + -18 Combine like terms: 18 + -18 = 0 0 + x = -16.970562748 + -18 x = -16.970562748 + -18 Combine like terms: -16.970562748 + -18 = -34.970562748 x = -34.970562748 Simplifying x = -34.970562748Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.029437252, -34.970562748}
