$\frac{x-6}{x+15} +\frac{x-15}{x+6}=0\\\\\frac{(x-6)(x+6)+(x-15)(x+15)}{(x+15)(x+6)}=0\\\\\frac{x^{2}-36+x^{2}-225}{(x+15)(x+6)}=0\\\\\frac{2x^{2}-261 }{(x+15)(x+6)}=0\\\\2x^{2}-261=0 \ ,x\neq -15 \ x\neq-6\\\\x^{2}=\frac{261}{2}\\\\x_{1,2}=\pm\sqrt{\frac{261}{2}}\\\\x_{1}*x_{2}=-\sqrt{\frac{261}{2}}*\sqrt{\frac{261}{2}}=-\sqrt{(\frac{261}{2} )^{2}}=-\frac{261}{2}=\boxed{-130,5}$
