Simplifying x2 + -2 = -8x Reorder the terms: -2 + x2 = -8x Solving -2 + x2 = -8x Solving for variable 'x'. Reorder the terms: -2 + 8x + x2 = -8x + 8x Combine like terms: -8x + 8x = 0 -2 + 8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 8x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 8x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 8x + x2 = 0 + 2 8x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 8x + x2 = 2 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = 2 + 16 Reorder the terms: 16 + 8x + x2 = 2 + 16 Combine like terms: 2 + 16 = 18 16 + 8x + x2 = 18 Factor a perfect square on the left side: (x + 4)(x + 4) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (x + 4) equal to 4.242640687 and -4.242640687.Subproblem 1
x + 4 = 4.242640687 Simplifying x + 4 = 4.242640687 Reorder the terms: 4 + x = 4.242640687 Solving 4 + x = 4.242640687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 4.242640687 + -4 Combine like terms: 4 + -4 = 0 0 + x = 4.242640687 + -4 x = 4.242640687 + -4 Combine like terms: 4.242640687 + -4 = 0.242640687 x = 0.242640687 Simplifying x = 0.242640687Subproblem 2
x + 4 = -4.242640687 Simplifying x + 4 = -4.242640687 Reorder the terms: 4 + x = -4.242640687 Solving 4 + x = -4.242640687 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -4.242640687 + -4 Combine like terms: 4 + -4 = 0 0 + x = -4.242640687 + -4 x = -4.242640687 + -4 Combine like terms: -4.242640687 + -4 = -8.242640687 x = -8.242640687 Simplifying x = -8.242640687Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.242640687, -8.242640687}
