Simplifying 2cos2x + -2cos = 0 Reorder the terms: -2cos + 2cos2x = 0 Solving -2cos + 2cos2x = 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), '2cos'. 2cos(-1 + sx) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'cos' equal to zero and attempt to solve: Simplifying cos = 0 Solving cos = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cos = 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 + sx)' equal to zero and attempt to solve: Simplifying -1 + sx = 0 Solving -1 + sx = 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 + sx = 0 + 1 Combine like terms: -1 + 1 = 0 0 + sx = 0 + 1 sx = 0 + 1 Combine like terms: 0 + 1 = 1 sx = 1 Add '-1sx' to each side of the equation. sx + -1sx = 1 + -1sx Combine like terms: sx + -1sx = 0 0 = 1 + -1sx Simplifying 0 = 1 + -1sx 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.
