You meant
\n" ); document.write( "f(x)=(5x^3+49x^2+127x+75)/(x^2+9x+18)=\"%285x%5E3%2B49x%5E2%2B127x%2B75%29%2F%28x%5E2%2B9x%2B18%29\"
\n" ); document.write( "
\n" ); document.write( "Factoring, we get \"x%5E2%2B9x%2B18=%28x%2B6%29%28x%2B3%29\",
\n" ); document.write( "and \"5x%5E3%2B49x%5E2%2B127x%2B75\" is divisible by \"x%2B3\"
\n" ); document.write( "\"5x%5E3%2B49x%5E2%2B127x%2B75=%285x%5E2%2B34x%2B25%29%28x%2B3%29\", so
\n" ); document.write( "
\n" ); document.write( "So, \"highlight%28x=-3%29\" and \"highlight%28x=-6%29\" are vertical asymptotes,
\n" ); document.write( "and for \"x%3C%3E-3\", \"f%28x%29=%285x%5E2%2B34x%2B25%29%2F%28x%2B6%29\"
\n" ); document.write( "
\n" ); document.write( "If we divide \"5x%5E2%2B34x%2B25\" by \"x%2B6\",
\n" ); document.write( "the quotient is \"5x%2B4\" and the remainder is \"1\".
\n" ); document.write( "In other words \"5x%5E2%2B34x%2B25=%28x%2B6%29%285x%2B4%29%2B1\"
\n" ); document.write( "So for \"x%3C-6\" and for \"x%3E0\",
\n" ); document.write( " approaches \"y=5x%2B4\" as \"abs%28x%29\" increases.
\n" ); document.write( "So \"highlight%28y=5x%2B4%29\" is the slant asymptote on both sides.
\n" ); document.write( "
\n" ); document.write( "IMPORTANT NOTE:
\n" ); document.write( "Those parentheses are essential if you cannot type the equation as the \"two-story\" version,
\n" ); document.write( "\"f%28x%29=%285x%5E3%2B49x%5E2%2B127x%2B75%29%2F%28x%5E2%2B9x%2B18%29\", with a long horizontal line in the middle.
\n" ); document.write( "The horizontal line implies the parentheses.
\n" ); document.write( "Without the parentheses, you get
\n" ); document.write( "f(x)=5x^3+49x^2+127x+75/x^2+9x+18=\"5x%5E3%2B49x%5E2%2B127x%2B75%2Fx%5E2%2B9x%2B18\"
\n" ); document.write( "
\n" );
