you will notice that middle terms add up to zero, so you are only left with \[x^6y^4\]

each cell is the result of multiplying the corresponding row and column headers so the upper left cell is the result of multiplying the two x^3 terms the upper right cell is the result of multiplying x^3 and y^2 etc etc giving you this dw:1362367968379:dw

then you add up all the terms and combine like terms if you can to get x^6  y^4 (the x^3y^2 terms will cancel as you got before)
