\"%28d-5%29%2F%283-d%29\" is undefined when the denominator \"3-d\" is equal to zero (since division by zero is NOT allowed). So simply find the value(s) of 'd' that make \"3-d=0\" true (ie solve that equation for 'd') to find the values that make the rational expression undefined. \n" ); document.write( "
