Subproblem 1

Set the factor '(1 + x + -4x2)' equal to zero and attempt to solve: Simplifying 1 + x + -4x2 = 0 Solving 1 + x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.25 + -0.25x + x2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + -0.25x + 0.25 + x2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + -0.25x + x2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + -0.25x + x2 = 0 + 0.25 -0.25x + x2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 -0.25x + x2 = 0.25 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -0.25x + 0.25 + x2 = 0.25 + 0.25 Reorder the terms: 0.25 + -0.25x + x2 = 0.25 + 0.25 Combine like terms: 0.25 + 0.25 = 0.5 0.25 + -0.25x + x2 = 0.5 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.5 Calculate the square root of the right side: 0.707106781 Break this problem into two subproblems by setting (x + 0.5) equal to 0.707106781 and -0.707106781.

Subproblem 1

x + 0.5 = 0.707106781 Simplifying x + 0.5 = 0.707106781 Reorder the terms: 0.5 + x = 0.707106781 Solving 0.5 + x = 0.707106781 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 0.707106781 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.707106781 + -0.5 x = 0.707106781 + -0.5 Combine like terms: 0.707106781 + -0.5 = 0.207106781 x = 0.207106781 Simplifying x = 0.207106781

Subproblem 2
