Subproblem 1

Set the factor '(6 + x + 10x2)' equal to zero and attempt to solve: Simplifying 6 + x + 10x2 = 0 Solving 6 + x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.6 + 0.1x + x2 = 0.0 Move the constant term to the right: Add '-0.6' to each side of the equation. 0.6 + 0.1x + -0.6 + x2 = 0.0 + -0.6 Reorder the terms: 0.6 + -0.6 + 0.1x + x2 = 0.0 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + 0.1x + x2 = 0.0 + -0.6 0.1x + x2 = 0.0 + -0.6 Combine like terms: 0.0 + -0.6 = -0.6 0.1x + x2 = -0.6 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. 0.1x + 0.25 + x2 = -0.6 + 0.25 Reorder the terms: 0.25 + 0.1x + x2 = -0.6 + 0.25 Combine like terms: -0.6 + 0.25 = -0.35 0.25 + 0.1x + x2 = -0.35 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -0.35 Can't calculate square root of the right side.
