Find the LCM of the polynomial \[{{\left( 3x+\text{ }y \right)}^{2}}-{{\left( 2x\text{ }-\text{ }y \right)}^{2}}and\text{ }{{\left( 7x\text{ }+\text{ }3y \right)}^{2}}-\text{ }{{\left( 6x\text{ }+\text{ }y \right)}^{2}}\]

A) \[5x\text{ }\left( x\text{ }+\text{ }2y \right)\text{ }\left( 13x\text{ }+\text{ }4y \right)\]           

B) \[\left( 7x\text{ }+\text{ }3y \right)\text{ }\left( 2x\text{ }+\text{ }y \right)\text{ }\left( 3x\text{ }+\text{ }y \right)\]

C) \[6x\text{ }\left( 3x\text{ }+\text{ }y \right)\text{ }\left( 7x\text{ }+\text{ }3y \right)\]            

D) \[\left( 3x\text{ }+\text{ }5y \right)\text{ }\left( 2x\text{ }+\text{ }3y \right)\text{ }7x\]

E) None of these
