sin(4x)+sin(2x)-sin(x)=0

Solution for sin(4x)+sin(2x)-sin(x)=0 equation:

Simplifying
sin(4x) + sin(2x) + -1sin(x) = 0

Remove parenthesis around (4x)
ins * 4x + sin(2x) + -1sin(x) = 0

Reorder the terms for easier multiplication:
4ins * x + sin(2x) + -1sin(x) = 0

Multiply ins * x
4insx + sin(2x) + -1sin(x) = 0

Remove parenthesis around (2x)
4insx + ins * 2x + -1sin(x) = 0

Reorder the terms for easier multiplication:
4insx + 2ins * x + -1sin(x) = 0

Multiply ins * x
4insx + 2insx + -1sin(x) = 0

Multiply ins * x
4insx + 2insx + -1insx = 0

Combine like terms: 4insx + 2insx = 6insx
6insx + -1insx = 0

Combine like terms: 6insx + -1insx = 5insx
5insx = 0
