we are given
\n" ); document.write( "(xy^3+3x^3y)-(6xy^3-6x^3y)
\n" ); document.write( "rewrite without parenthesis
\n" ); document.write( "xy^3 + 3x^3y - 6xy^3 + 6x^3y
\n" ); document.write( "combine like terms
\n" ); document.write( "-5xy^3 + 9x^3y
\n" ); document.write( "
\n" ); document.write( "
\n" );
