Subproblem 1

Set the factor 'x7' equal to zero and attempt to solve: Simplifying x7 = 0 Solving x7 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x7 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(24 + 3x + x2)' equal to zero and attempt to solve: Simplifying 24 + 3x + x2 = 0 Solving 24 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-24' to each side of the equation. 24 + 3x + -24 + x2 = 0 + -24 Reorder the terms: 24 + -24 + 3x + x2 = 0 + -24 Combine like terms: 24 + -24 = 0 0 + 3x + x2 = 0 + -24 3x + x2 = 0 + -24 Combine like terms: 0 + -24 = -24 3x + x2 = -24 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 = -24 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -24 + 2.25 Combine like terms: -24 + 2.25 = -21.75 2.25 + 3x + x2 = -21.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = -21.75 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.
