Simplifying cos2(x) + 5cos = 0 Multiply cos2 * x cos2x + 5cos = 0 Reorder the terms: 5cos + cos2x = 0 Solving 5cos + cos2x = 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(5 + sx) = 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 '(5 + sx)' equal to zero and attempt to solve: Simplifying 5 + sx = 0 Solving 5 + sx = 0 Move all terms containing c to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + sx = 0 + -5 Combine like terms: 5 + -5 = 0 0 + sx = 0 + -5 sx = 0 + -5 Combine like terms: 0 + -5 = -5 sx = -5 Add '-1sx' to each side of the equation. sx + -1sx = -5 + -1sx Combine like terms: sx + -1sx = 0 0 = -5 + -1sx Simplifying 0 = -5 + -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.
