Set the factor 'x3' equal to zero and attempt to solve: Simplifying x3 = 0 Solving x3 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(1 + -8x + 2x2)' equal to zero and attempt to solve: Simplifying 1 + -8x + 2x2 = 0 Solving 1 + -8x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 0.5 + -4x + x2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -4x + -0.5 + x2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -4x + x2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -4x + x2 = 0 + -0.5 -4x + x2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -4x + x2 = -0.5 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 = -0.5 + 4 Reorder the terms: 4 + -4x + x2 = -0.5 + 4 Combine like terms: -0.5 + 4 = 3.5 4 + -4x + x2 = 3.5 Factor a perfect square on the left side: (x + -2)(x + -2) = 3.5 Calculate the square root of the right side: 1.870828693 Break this problem into two subproblems by setting (x + -2) equal to 1.870828693 and -1.870828693.Subproblem 1
x + -2 = 1.870828693 Simplifying x + -2 = 1.870828693 Reorder the terms: -2 + x = 1.870828693 Solving -2 + x = 1.870828693 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 = 1.870828693 + 2 Combine like terms: -2 + 2 = 0 0 + x = 1.870828693 + 2 x = 1.870828693 + 2 Combine like terms: 1.870828693 + 2 = 3.870828693 x = 3.870828693 Simplifying x = 3.870828693Subproblem 2
x + -2 = -1.870828693 Simplifying x + -2 = -1.870828693 Reorder the terms: -2 + x = -1.870828693 Solving -2 + x = -1.870828693 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 = -1.870828693 + 2 Combine like terms: -2 + 2 = 0 0 + x = -1.870828693 + 2 x = -1.870828693 + 2 Combine like terms: -1.870828693 + 2 = 0.129171307 x = 0.129171307 Simplifying x = 0.129171307Solution
