(-7b^3+2b-3)(5b^2-2b+4)
\n" ); document.write( "first you multiply everything in the second trinomial by the first term in the first trinomial
\n" ); document.write( "-35b^5+14b^4-28b^3
\n" ); document.write( "then add on to that everything in the second trinomial multiplied by the second term in the first trinomial
\n" ); document.write( "-35b^5+14b^4-28b^3+10b^3-4b^2+8b
\n" ); document.write( "then add on to that everything in the second trinomial multiplied by the third term in the first trinomial
\n" ); document.write( "-35b^5+14b^4-28b^3+10b^3-4b^2+8b-15b^2+6b-12
\n" ); document.write( "then put the terms in decreasing degree order
\n" ); document.write( "-35b^5+14b^4-28b^3+10b^3-4b^2-15b^2+8b+6b-12
\n" ); document.write( "then combine like terms to finish simplifying the problem
\n" ); document.write( "-35b^5+14b^4-18b^3-19b^2+14b-12 \n" ); document.write( "

\n" );
