Subproblem 1

Set the factor '(30 + 5x + x2)' equal to zero and attempt to solve: Simplifying 30 + 5x + x2 = 0 Solving 30 + 5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + 5x + -30 + x2 = 0 + -30 Reorder the terms: 30 + -30 + 5x + x2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + 5x + x2 = 0 + -30 5x + x2 = 0 + -30 Combine like terms: 0 + -30 = -30 5x + x2 = -30 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = -30 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -30 + 6.25 Combine like terms: -30 + 6.25 = -23.75 6.25 + 5x + x2 = -23.75 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = -23.75 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.
