A school designer wants to create a whiteboard with the optimal dimensions to enhance learning. It is determined that if ONE side of the whiteboard is x+y inches, the other side should be x^2-3xy+7y^2 inches. WRITE an algebraic expression for the area of such a whiteboard, SIMPLIFY it, and INCLUDE correct UNITS with your solutions.

\n" ); document.write( "Area = L*W
\n" ); document.write( " $\"Area+=+%28x%2By%29%2A%28x%5E2-3xy%2B7y%5E2%29\"$
\n" ); document.write( " $\"Area+=+x%5E3+-+2x%5E2y+%2B+4xy%5E2+%2B+7y%5E3\"$ sq inches
\n" ); document.write( "No \"simplification\" is possible.\r
