\"+5x%5E2y%5E6z%5E4-15x%5E4y%5E5z%5E3%2B20x%5E3y%5E5z%5E2\"
\n" ); document.write( "look for the greatest common factors in each term and then use distribution to \"pull them out\"
\n" ); document.write( "\"+5x%5E2y%5E5z%5E2+%28yz%5E2+-3x%5E2z+%2B4x%29+\"\r
\n" ); document.write( "\n" ); document.write( "Same idea for problem 2
\n" ); document.write( "\"12xy%2B20yz-40wy\"
\n" ); document.write( "\"4y%2A%283x+%2B+5z+-+10w%29\"\r
\n" ); document.write( "\n" ); document.write( "For number 3, use difference of two squares
\n" ); document.write( "\"16x%5E2-49\"
\n" ); document.write( "\"%284x+-+7%29%284x%2B7%29\"
