\[\frac{2}{x+3}-\frac{6}{x-3}=\frac{12}{x^2-9}\]
multiply both sides by \[x^2-9\]
on the right you will get 12. on the left you will get \[2(x-3)-6(x+3)\] because \[x^2-9=(x+3)(x-3)\]
so the factors will cancel. now solve \[2(x-3)-6(x+3)=12\] \[2x-6-6x-18=12\] \[-4x-24=12\] \[-4x=12+24=36\] \[x=\frac{36}{-4}=-9\]
let me check it to makes sure i didn't make a mistake
