Subproblem 1

Set the factor '(6 + -1x + 2x2)' equal to zero and attempt to solve: Simplifying 6 + -1x + 2x2 = 0 Solving 6 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3 + -0.5x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + -0.5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -0.5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -0.5x + x2 = 0 + -3 -0.5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -0.5x + x2 = -3 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = -3 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -3 + 0.0625 Combine like terms: -3 + 0.0625 = -2.9375 0.0625 + -0.5x + x2 = -2.9375 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -2.9375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
