RMO Rules

Prove that when (x+1)n(x+1)^{n} is divided by (x1)3(x-1)^{3}. The remainder is n(n1)(2n3)(x2)2n2x(n23n)+2n3(n25n+8)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.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
