Ignore the factor 3.

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 '(6 + -1x + x2)' equal to zero and attempt to solve: Simplifying 6 + -1x + x2 = 0 Solving 6 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + -1x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -1x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x + x2 = 0 + -6 -1x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -1x + x2 = -6 The x term is -1x. 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. -1x + 0.25 + x2 = -6 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -6 + 0.25 Combine like terms: -6 + 0.25 = -5.75 0.25 + -1x + x2 = -5.75 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -5.75 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.
