Simplifying -3cos3x + -2cosx = 0 Reorder the terms: -2cosx + -3cos3x = 0 Solving -2cosx + -3cos3x = 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), '-1cosx'. -1cosx(2 + 3s2) = 0 Ignore the factor -1.Subproblem 1
Set the factor 'cosx' equal to zero and attempt to solve: Simplifying cosx = 0 Solving cosx = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cosx = 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 '(2 + 3s2)' equal to zero and attempt to solve: Simplifying 2 + 3s2 = 0 Solving 2 + 3s2 = 0 Move all terms containing c to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 3s2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3s2 = 0 + -2 3s2 = 0 + -2 Combine like terms: 0 + -2 = -2 3s2 = -2 Add '-3s2' to each side of the equation. 3s2 + -3s2 = -2 + -3s2 Combine like terms: 3s2 + -3s2 = 0 0 = -2 + -3s2 Simplifying 0 = -2 + -3s2 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.
