Simplifying 4cos2(x) + -6cos(x) = 4 Multiply cos2 * x 4cos2x + -6cos(x) = 4 Multiply cos * x 4cos2x + -6cosx = 4 Reorder the terms: -6cosx + 4cos2x = 4 Solving -6cosx + 4cos2x = 4 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Reorder the terms: -4 + -6cosx + 4cos2x = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + -6cosx + 4cos2x = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-2 + -3cosx + 2cos2x) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-2 + -3cosx + 2cos2x)' equal to zero and attempt to solve: Simplifying -2 + -3cosx + 2cos2x = 0 Solving -2 + -3cosx + 2cos2x = 0 Move all terms containing c to the left, all other terms to the right. Add '2' to each side of the equation. -2 + -3cosx + 2 + 2cos2x = 0 + 2 Reorder the terms: -2 + 2 + -3cosx + 2cos2x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -3cosx + 2cos2x = 0 + 2 -3cosx + 2cos2x = 0 + 2 Combine like terms: 0 + 2 = 2 -3cosx + 2cos2x = 2 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.
