• Source of this question, please? – Gerry Myerson Mar 10 '17 at 9:53
• A Book, but solution for that particular book is not provided – Stephan_Mc007 Mar 10 '17 at 11:19
• Which book, please? – Gerry Myerson Mar 10 '17 at 12:18
• Mathematics Higher Level - Nigel Buckle, et.al – Stephan_Mc007 Mar 10 '17 at 12:47
• Seems like a strange question for a textbook, especially if there's nothing in the book explaining how to do polynomial operations in binary. I'd suggest calculating $A^2,A^3,A^4$ to see whether any pattern emerges. – Gerry Myerson Mar 10 '17 at 21:50
