Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(36 + F + -4x2)' equal to zero and attempt to solve: Simplifying 36 + F + -4x2 = 0 Solving 36 + F + -4x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-36' to each side of the equation. 36 + F + -36 + -4x2 = 0 + -36 Reorder the terms: 36 + -36 + F + -4x2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + F + -4x2 = 0 + -36 F + -4x2 = 0 + -36 Combine like terms: 0 + -36 = -36 F + -4x2 = -36 Add '-1F' to each side of the equation. F + -1F + -4x2 = -36 + -1F Combine like terms: F + -1F = 0 0 + -4x2 = -36 + -1F -4x2 = -36 + -1F Divide each side by '-4'. x2 = 9 + 0.25F Simplifying x2 = 9 + 0.25F The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
