You can put this solution on YOUR website!
\"4x%5E2-3x%5E2%2B5x-x%5E2-1\" Start with the given expression.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284x%5E2-3x%5E2-x%5E2%29%2B5x-1\" Group like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5x-1\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"4x%5E2-3x%5E2%2B5x-x%5E2-1=5x-1\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So you are correct.
\n" ); document.write( "
\n" );
