Solution for cos(x)=-2sin(x)cos(x) equation: 


Simplifying
cos(x) = -2sin(x) * cos(x)

Multiply cos * x
cosx = -2sin(x) * cos(x)

Multiply ins * x
cosx = -2insx * cos * x

Multiply insx * cos
cosx = -2cinos2x * x

Multiply cinos2x * x
cosx = -2cinos2x2

Solving
cosx = -2cinos2x2

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '2cinos2x2' to each side of the equation.
2cinos2x2 + cosx = -2cinos2x2 + 2cinos2x2

Combine like terms: -2cinos2x2 + 2cinos2x2 = 0
2cinos2x2 + cosx = 0

Factor out the Greatest Common Factor (GCF), 'cosx'.
cosx(2insx + 1) = 0
