One could also start by taking a and b out:\[a^{3}(xy)+b^{3}(yx)\] But I don't really know how to get to that answer or why to aim at that? :o

You can check that what abdul said by going backwards: \[(a  b)(a ^{2} + ab + b ^{2})\] \[= (a^{3}+a^{2}b + ab^{2}) + (a^{2}b  ab^{2}  b^{3})\] \[= a^{3}+a^{2}b  a^{2}b + ab^{2}  ab^{2}  b^{3}\] \[= a^{3}  b^{3}\] Not sure yet how to get that (x  y) out o.O

\[a^3xb^3xa^3y+b^3y\] \[x(a^3b^3)y(a^3b^3)\] \[(a^3b^3)(xy)\] \[(ab)(a^2+ab+b^2)(xy)\]
