Subproblem 1

Set the factor '(180 + -12x + x2)' equal to zero and attempt to solve: Simplifying 180 + -12x + x2 = 0 Solving 180 + -12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-180' to each side of the equation. 180 + -12x + -180 + x2 = 0 + -180 Reorder the terms: 180 + -180 + -12x + x2 = 0 + -180 Combine like terms: 180 + -180 = 0 0 + -12x + x2 = 0 + -180 -12x + x2 = 0 + -180 Combine like terms: 0 + -180 = -180 -12x + x2 = -180 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = -180 + 36 Reorder the terms: 36 + -12x + x2 = -180 + 36 Combine like terms: -180 + 36 = -144 36 + -12x + x2 = -144 Factor a perfect square on the left side: (x + -6)(x + -6) = -144 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.
