Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-1 + -4x + 2x2)' equal to zero and attempt to solve: Simplifying -1 + -4x + 2x2 = 0 Solving -1 + -4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + -2x + x2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -2x + 0.5 + x2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -2x + x2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -2x + x2 = 0 + 0.5 -2x + x2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -2x + x2 = 0.5 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 = 0.5 + 1 Reorder the terms: 1 + -2x + x2 = 0.5 + 1 Combine like terms: 0.5 + 1 = 1.5 1 + -2x + x2 = 1.5 Factor a perfect square on the left side: (x + -1)(x + -1) = 1.5 Calculate the square root of the right side: 1.224744871 Break this problem into two subproblems by setting (x + -1) equal to 1.224744871 and -1.224744871.

Subproblem 1

x + -1 = 1.224744871 Simplifying x + -1 = 1.224744871 Reorder the terms: -1 + x = 1.224744871 Solving -1 + x = 1.224744871 Solving for variable 'x'.
