Subproblem 1

Set the factor '(18 + 6x + x2)' equal to zero and attempt to solve: Simplifying 18 + 6x + x2 = 0 Solving 18 + 6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + 6x + -18 + x2 = 0 + -18 Reorder the terms: 18 + -18 + 6x + x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + 6x + x2 = 0 + -18 6x + x2 = 0 + -18 Combine like terms: 0 + -18 = -18 6x + x2 = -18 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -18 + 9 Reorder the terms: 9 + 6x + x2 = -18 + 9 Combine like terms: -18 + 9 = -9 9 + 6x + x2 = -9 Factor a perfect square on the left side: (x + 3)(x + 3) = -9 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.
