To find the difference of two expressions subtract one from the other:
\n" ); document.write( "\"%282x%5E2+%2B+4xy+-+3%29+-+%28x%5E2+-+2xy+-+4%29\"
\n" ); document.write( "Multiply the second parentheses by the negative:
\n" ); document.write( "\"2x%5E2+%2B+4xy+-+3+-+x%5E2+%2B+2xy+-+4\"
\n" ); document.write( "Combine like terms to find your answer:
\n" ); document.write( "\"x%5E2+%2B+6xy+-+7\"
\n" ); document.write( "
