# RMO Rules

Prove that when $(x+1)^{n}$ is divided by $(x-1)^{3}$. The remainder is $n\left( n-1 \right) \left( { 2 }^{ n-3 } \right) \left( { x }^{ 2 } \right) -{ 2 }^{ n-2 }x\left( { n }^{ 2 }-3n \right) +{ 2 }^{ n-3 }\left( { n }^{ 2 }-5n+8 \right)$

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
