You can put this solution on YOUR website!
(2c + d)(2c – d)\r
\n" ); document.write( "\n" ); document.write( "1-Use the FOIL method to solve. I'll assign each term a capital letter.
\n" ); document.write( " W X Y Z
\n" ); document.write( " (2c + d)(2c - d)
\n" ); document.write( "2-Multiply first terms W and Y. 2c x 2c = 4c^2
\n" ); document.write( "3-Multiply outer terms W and Z. 2c x -1d = -2cd
\n" ); document.write( "4-Multiply inner terms X and Y. d x 2c = 2cd
\n" ); document.write( "5-Multiply last terms X and Z. d x -d = -d^2
\n" ); document.write( "6-Lastly, combine your terms together.
\n" ); document.write( " 4c^2 - 2cd + 2cd - d^2
\n" ); document.write( "7-Your solution should by 4c^2-d^2 \n" ); document.write( "

\n" );
