[tex]\frac{3a^{3}-81 }{a^{4}+3a^{3} +3a^{2} }[/tex]
Объяснение:
[tex]\frac{a^{3}-27 }{a^{2}-2a } *\frac{3a-6}{a^{3} +3a^{2} +3a} \\\frac{a^{3}-27 }{a(a-2) } *\frac{3(a-2)}{a^{3} +3a^{2} +3a} \\\frac{a^{3}-27 }{a}*\frac{3}{a^{3} +3a^{2} +3a} \\\frac{3(a^{3}-27) }{a(a^{3} +3a^{2}+3a) } \\\\\frac{3a^{3}-81 }{a^{4}+3a^{3} +3a^{2} }[/tex]
