Помогите пожайлуйста!!!​

Answer 1

$1)\frac{m+4}{6-m}*\frac{m}{m+6} =\frac{m(m+4)}{(6-m)(m+6)}=\frac{m^{2}+4m }{36-m^{2}}\\\\2)\frac{8m+36}{m^{2}-36}-\frac{m^{2}+4m}{36-m^{2}}=\frac{8m+36}{m^{2}-36}+\frac{m^{2}+4m }{m^{2}-36}=\frac{m^{2}+12m+36}{m^{2}-36}=\frac{(m+6)^{2}}{(m+6)(m-6)}=\frac{m+6}{m-6}$
