Set the factor '(2 + x + x2)' equal to zero and attempt to solve: Simplifying 2 + x + x2 = 0 Solving 2 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x + x2 = 0 + -2 x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 x + x2 = -2 The x term is x. 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. x + 0.25 + x2 = -2 + 0.25 Reorder the terms: 0.25 + x + x2 = -2 + 0.25 Combine like terms: -2 + 0.25 = -1.75 0.25 + x + x2 = -1.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.75 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.
