Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2 if julian wrote the last term as –3x4, which must be the first term of his polynomial in standard form? 4y4 6y4 –2xy3 –10xy3

Trevor:  Be a sport and express exponentiation properly.  You must use the symbol       " ^ " for this purpose:

4x^2y^2 – 2y^4 – 8xy^3 + 9x3y + 6y^4 – 2xy^3 – 3x^4 + x2y^2

If Julian's last term is -3x^4, then the first term must be 6y^4.  Think about this and see whether you can detect a pattern.  The first term MUST contain "y" only and the last term MUST contain x only.
