Solving
28cinosx2S = -28cinos2x2
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '28cinos2x2' to each side of the equation.
28cinosx2S + 28cinos2x2 = -28cinos2x2 + 28cinos2x2
Combine like terms: -28cinos2x2 + 28cinos2x2 = 0
28cinosx2S + 28cinos2x2 = 0
Factor out the Greatest Common Factor (GCF), '28cinosx2'.
28cinosx2(S + s) = 0
Ignore the factor 28.

Subproblem 1

Set the factor 'cinosx2' equal to zero and attempt to solve: Simplifying cinosx2 = 0 Solving cinosx2 = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cinosx2 = 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 '(S + s)' equal to zero and attempt to solve: Simplifying S + s = 0 Solving S + s = 0 Move all terms containing c to the left, all other terms to the right. Add '-1S' to each side of the equation. S + -1S + s = 0 + -1S Combine like terms: S + -1S = 0 0 + s = 0 + -1S s = 0 + -1S Remove the zero: s = -1S Add '-1s' to each side of the equation. s + -1s = -1S + -1s Combine like terms: s + -1s = 0 0 = -1S + -1s Simplifying 0 = -1S + -1s 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.
