Simplifying cos2x + 2cosx = 3equation Reorder the terms: 2cosx + cos2x = 3equation Solving 2cosx + cos2x = 3aeinoqtu Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Reorder the terms: -3aeinoqtu + 2cosx + cos2x = 3aeinoqtu + -3aeinoqtu Combine like terms: 3aeinoqtu + -3aeinoqtu = 0 -3aeinoqtu + 2cosx + cos2x = 0 Factor out the Greatest Common Factor (GCF), 'o'. o(-3aeinqtu + 2csx + cs2x) = 0Subproblem 1
Set the factor 'o' equal to zero and attempt to solve: Simplifying o = 0 Solving o = 0 Move all terms containing c to the left, all other terms to the right. Add '-1o' to each side of the equation. o + -1o = 0 + -1o Remove the zero: 0 = -1o Simplifying 0 = -1o The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
