You can put this solution on YOUR website!
The expression for #4 is $\"-y%5E3-2y%5E2%2By-7\"$ , and you want to factorize using greatest common factor.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Notice very obviously, $\"-7\"$ does NOT have a factor of y.
\n" ); document.write( "Here are the complete factorizations of the terms in the expression:
\n" ); document.write( "

\r\n" );
document.write( "-1*y*y*y\r\n" );
document.write( "-2*y*y\r\n" );
document.write( "y\r\n" );
document.write( "-1*7\r\n" );
document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There seems to be no common factor among those terms, but you can view $\"y\"$ , if you want, as $\"%28-1%29%28-1%29y\"$ , just so you may have $\"-1\"$ multiplied by an otherwise expression with a positive leading term of degree three. If you do this then you can give $\"%28-1%29%28y%5E3%2B2y%5E2-y%2B7%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "~~If you wanted to factorize with y, then you no longer have just a polynomial.~~ You might have $\"-1%2Ay%28y%5E2%2B2y-1%2B7%2Fy%29\"$ but this is not so convenient a factorization because one of these factors is not polynomial. \n" ); document.write( "

\n" );
