Simplifying 2cos2 + -1cosx = 0 Reorder the terms: -1cosx + 2cos2 = 0 Solving -1cosx + 2cos2 = 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), 'cos'. cos(-1x + 2s) = 0Subproblem 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 '(-1x + 2s)' equal to zero and attempt to solve: Simplifying -1x + 2s = 0 Reorder the terms: 2s + -1x = 0 Solving 2s + -1x = 0 Move all terms containing c to the left, all other terms to the right. Add '-2s' to each side of the equation. 2s + -2s + -1x = 0 + -2s Combine like terms: 2s + -2s = 0 0 + -1x = 0 + -2s -1x = 0 + -2s Remove the zero: -1x = -2s Add 'x' to each side of the equation. -1x + x = -2s + x Combine like terms: -1x + x = 0 0 = -2s + x Simplifying 0 = -2s + x 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.
