You can put this solution on YOUR website!
You need to multiply 2x times everything in the second parenthesis and then multiply -1 time everything in the second parenthesis and then combine like terms. Like terms are terms that have the very same variables to the very same power:
\n" ); document.write( "(2x-1)(10x+1)
\n" ); document.write( "\"2x%2810x%29%2B2x%281%29-1%2810x%29-1%281%29\"
\n" ); document.write( "\"20x%5E2%2B2x-10x-1\"
\n" ); document.write( "\"20x%5E2%2B%282-10%29x-1\"
\n" ); document.write( "\"highlight%2820x%5E2-8x-1%29\"
\n" ); document.write( "Happy Calculating!!!
\n" ); document.write( "
\n" );
