Simplifying 0 = -2x2 + 4x + 2 Reorder the terms: 0 = 2 + 4x + -2x2 Solving 0 = 2 + 4x + -2x2 Solving for variable 'x'. Combine like terms: 0 + -2 = -2 -2 + -4x + 2x2 = 2 + 4x + -2x2 + -2 + -4x + 2x2 Reorder the terms: -2 + -4x + 2x2 = 2 + -2 + 4x + -4x + -2x2 + 2x2 Combine like terms: 2 + -2 = 0 -2 + -4x + 2x2 = 0 + 4x + -4x + -2x2 + 2x2 -2 + -4x + 2x2 = 4x + -4x + -2x2 + 2x2 Combine like terms: 4x + -4x = 0 -2 + -4x + 2x2 = 0 + -2x2 + 2x2 -2 + -4x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 -2 + -4x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-1 + -2x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-1 + -2x + x2)' equal to zero and attempt to solve: Simplifying -1 + -2x + x2 = 0 Solving -1 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -2x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -2x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -2x + x2 = 0 + 1 -2x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -2x + x2 = 1 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 1 + 1 Reorder the terms: 1 + -2x + x2 = 1 + 1 Combine like terms: 1 + 1 = 2 1 + -2x + x2 = 2 Factor a perfect square on the left side: (x + -1)(x + -1) = 2 Calculate the square root of the right side: 1.414213562 Break this problem into two subproblems by setting (x + -1) equal to 1.414213562 and -1.414213562.Subproblem 1
x + -1 = 1.414213562 Simplifying x + -1 = 1.414213562 Reorder the terms: -1 + x = 1.414213562 Solving -1 + x = 1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.414213562 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.414213562 + 1 x = 1.414213562 + 1 Combine like terms: 1.414213562 + 1 = 2.414213562 x = 2.414213562 Simplifying x = 2.414213562Subproblem 2
x + -1 = -1.414213562 Simplifying x + -1 = -1.414213562 Reorder the terms: -1 + x = -1.414213562 Solving -1 + x = -1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.414213562 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.414213562 + 1 x = -1.414213562 + 1 Combine like terms: -1.414213562 + 1 = -0.414213562 x = -0.414213562 Simplifying x = -0.414213562Solution
