Subproblem 1

Set the factor '(40 + 4x + x2)' equal to zero and attempt to solve: Simplifying 40 + 4x + x2 = 0 Solving 40 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-40' to each side of the equation. 40 + 4x + -40 + x2 = 0 + -40 Reorder the terms: 40 + -40 + 4x + x2 = 0 + -40 Combine like terms: 40 + -40 = 0 0 + 4x + x2 = 0 + -40 4x + x2 = 0 + -40 Combine like terms: 0 + -40 = -40 4x + x2 = -40 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = -40 + 4 Reorder the terms: 4 + 4x + x2 = -40 + 4 Combine like terms: -40 + 4 = -36 4 + 4x + x2 = -36 Factor a perfect square on the left side: (x + 2)(x + 2) = -36 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.
