Subproblem 1

Set the factor '(22 + 3x + x2)' equal to zero and attempt to solve: Simplifying 22 + 3x + x2 = 0 Solving 22 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-22' to each side of the equation. 22 + 3x + -22 + x2 = 0 + -22 Reorder the terms: 22 + -22 + 3x + x2 = 0 + -22 Combine like terms: 22 + -22 = 0 0 + 3x + x2 = 0 + -22 3x + x2 = 0 + -22 Combine like terms: 0 + -22 = -22 3x + x2 = -22 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 = -22 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -22 + 2.25 Combine like terms: -22 + 2.25 = -19.75 2.25 + 3x + x2 = -19.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = -19.75 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.
