How would you factor -2sin(4x)sin(x)-sin(4x)=0?

0 votes

I know how to find the solutions, just the factoring that I'm not used to on this one.

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

[-sin(4x)][2sin(x) + 1] = 0

[sin(4x)][2sin(x)+1] = 0

Factoring of -2sin(4x)Sin(x)-sin(4x) = 0 is [sin(4x)][2sin(x)+1] = 0
