Starting with the expression:


15x-30x

First, notice that both terms have a common factor of x. Therefore, rewrite the expression as:


15x-30x=x(15-30)

Next, notice that 30=15*2. Therefore, both 15 and 30 have a common factor of 15. Rewrite the expression again factoring out 15:


\begin{gathered} x(15-30)=x\lbrack15(1-2)\rbrack \\ =15x(1-2) \end{gathered}

Since the greatest factor of 1 is 1, then the expression has no further common factors.

Therefore, the greatest common factor is 15x.


(15x)/(15x)-(30x)/(15x)=1-2

The final factored expression would be:


15x(1-2)
