Subproblem 1

Set the factor '(18 + -7x + x2)' equal to zero and attempt to solve: Simplifying 18 + -7x + x2 = 0 Solving 18 + -7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + -7x + -18 + x2 = 0 + -18 Reorder the terms: 18 + -18 + -7x + x2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -7x + x2 = 0 + -18 -7x + x2 = 0 + -18 Combine like terms: 0 + -18 = -18 -7x + x2 = -18 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = -18 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -18 + 12.25 Combine like terms: -18 + 12.25 = -5.75 12.25 + -7x + x2 = -5.75 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = -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. The solution to this equation could not be determined.
