Solution for Tan(3x)(tan-1)=0 equation: 


Simplifying
Tan(3x)(tan + -1) = 0

Remove parenthesis around (3x)
anT * 3x(tan + -1) = 0

Reorder the terms:
anT * 3x(-1 + ant) = 0

Reorder the terms for easier multiplication:
3anT * x(-1 + ant) = 0

Multiply anT * x
3anxT(-1 + ant) = 0
(-1 * 3anxT + ant * 3anxT) = 0
(-3anxT + 3a2n2txT) = 0

Solving
-3anxT + 3a2n2txT = 0

Solving for variable 'a'.

Factor out the Greatest Common Factor (GCF), '3anxT'.
3anxT(-1 + ant) = 0

Ignore the factor 3.
