one side of the whiteboard is x + 4y inches, the other side should be x^2 + 4xy - 6y^2 inches
:
. . . x^2 + 4xy - 6y^2
. . . X. . . . . x + 4y
---------------------------
. . . 4x^2y + 16xy^2 - 24y^3
. x^3 + 4x^2y - 6xy^2
------------------------------
. x^3 + 8x^2y + 10xy^2 - 24y^3 = the area of the board
