Simplifying Cos * 2x = -1cosx Reorder the terms for easier multiplication: 2osC * x = -1cosx Multiply osC * x 2osxC = -1cosx Solving 2osxC = -1cosx Solving for variable 'o'. Move all terms containing o to the left, all other terms to the right. Add 'cosx' to each side of the equation. cosx + 2osxC = -1cosx + cosx Combine like terms: -1cosx + cosx = 0 cosx + 2osxC = 0 Factor out the Greatest Common Factor (GCF), 'osx'. osx(c + 2C) = 0Subproblem 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 '(c + 2C)' equal to zero and attempt to solve: Simplifying c + 2C = 0 Reorder the terms: 2C + c = 0 Solving 2C + c = 0 Move all terms containing o to the left, all other terms to the right. Add '-2C' to each side of the equation. 2C + -2C + c = 0 + -2C Combine like terms: 2C + -2C = 0 0 + c = 0 + -2C c = 0 + -2C Remove the zero: c = -2C Add '-1c' to each side of the equation. c + -1c = -2C + -1c Combine like terms: c + -1c = 0 0 = -2C + -1c Simplifying 0 = -2C + -1c 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.
