Subproblem 1

Set the factor '(6 + -3x + x2)' equal to zero and attempt to solve: Simplifying 6 + -3x + x2 = 0 Solving 6 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + -3x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -3x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -3x + x2 = 0 + -6 -3x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -3x + x2 = -6 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -6 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -6 + 2.25 Combine like terms: -6 + 2.25 = -3.75 2.25 + -3x + x2 = -3.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -3.75 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.
