\n" ); document.write( "Use synthetic division to make the work easier than polynomial long division.

\r\n" );
document.write( "\r\n" );
document.write( "   -5 | 1   7  13  22\r\n" );
document.write( "      |    -5 -10 -15\r\n" );
document.write( "      ---------------\r\n" );
document.write( "        1   2   3   7

\n" ); document.write( "The quotient is x^2+2x+3 and the remainder is 7. So

\n" ); document.write( "x^3+7x^2+13x+22 = (x+5)(x^2+2x+3) + 7 \n" ); document.write( "
