Simplifying x2 + 4x + 2 = 8 Reorder the terms: 2 + 4x + x2 = 8 Solving 2 + 4x + x2 = 8 Solving for variable 'x'. Reorder the terms: 2 + -8 + 4x + x2 = 8 + -8 Combine like terms: 2 + -8 = -6 -6 + 4x + x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -6 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + 4x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + 4x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 4x + x2 = 0 + 6 4x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 4x + x2 = 6 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 = 6 + 4 Reorder the terms: 4 + 4x + x2 = 6 + 4 Combine like terms: 6 + 4 = 10 4 + 4x + x2 = 10 Factor a perfect square on the left side: (x + 2)(x + 2) = 10 Calculate the square root of the right side: 3.16227766 Break this problem into two subproblems by setting (x + 2) equal to 3.16227766 and -3.16227766.Subproblem 1
x + 2 = 3.16227766 Simplifying x + 2 = 3.16227766 Reorder the terms: 2 + x = 3.16227766 Solving 2 + x = 3.16227766 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 = 3.16227766 + -2 Combine like terms: 2 + -2 = 0 0 + x = 3.16227766 + -2 x = 3.16227766 + -2 Combine like terms: 3.16227766 + -2 = 1.16227766 x = 1.16227766 Simplifying x = 1.16227766Subproblem 2
x + 2 = -3.16227766 Simplifying x + 2 = -3.16227766 Reorder the terms: 2 + x = -3.16227766 Solving 2 + x = -3.16227766 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 = -3.16227766 + -2 Combine like terms: 2 + -2 = 0 0 + x = -3.16227766 + -2 x = -3.16227766 + -2 Combine like terms: -3.16227766 + -2 = -5.16227766 x = -5.16227766 Simplifying x = -5.16227766Solution
