\n" ); document.write( "\n" ); document.write( " $\"%286%29%2F%282n%2B4%29\"$ Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2n%2B4=0\"$ Set the denominator equal to zero. Remember, dividing by 0 is undefined.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2n=0-4\"$ Subtract 4 from both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2n=-4\"$ Combine like terms on the right side\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"n=%28-4%29%2F%282%29\"$ Divide both sides by 2 to isolate n\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"n=-2\"$ Divide\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So if $\"n=-2\"$ , then the expression $\"%286%29%2F%282n%2B4%29\"$ is undefined.
\n" ); document.write( " \n" ); document.write( "
