Simplifying cos2x + -1cos5x = 0 Solving cos2x + -1cos5x = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), 'cos2x'. cos2x(1 + -1s3) = 0Subproblem 1
Set the factor 'cos2x' equal to zero and attempt to solve: Simplifying cos2x = 0 Solving cos2x = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cos2x = 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 '(1 + -1s3)' equal to zero and attempt to solve: Simplifying 1 + -1s3 = 0 Solving 1 + -1s3 = 0 Move all terms containing c to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1s3 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1s3 = 0 + -1 -1s3 = 0 + -1 Combine like terms: 0 + -1 = -1 -1s3 = -1 Add 's3' to each side of the equation. -1s3 + s3 = -1 + s3 Combine like terms: -1s3 + s3 = 0 0 = -1 + s3 Simplifying 0 = -1 + s3 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.
