Subproblem 1

Set the factor 'osx' equal to zero and attempt to solve: Simplifying osx = 0 Solving osx = 0 Move all terms containing o to the left, all other terms to the right. Simplifying osx = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(-4cs + C)' equal to zero and attempt to solve: Simplifying -4cs + C = 0 Reorder the terms: C + -4cs = 0 Solving C + -4cs = 0 Move all terms containing o to the left, all other terms to the right. Add '-1C' to each side of the equation. C + -1C + -4cs = 0 + -1C Combine like terms: C + -1C = 0 0 + -4cs = 0 + -1C -4cs = 0 + -1C Remove the zero: -4cs = -1C Add '4cs' to each side of the equation. -4cs + 4cs = -1C + 4cs Combine like terms: -4cs + 4cs = 0 0 = -1C + 4cs Simplifying 0 = -1C + 4cs 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.
