This question is difficult to answer.和This question is difficult for answering哪个是对的
不要用翻译机.
讲一下为什么

both of them are right

第一个是对的,因为句式sth+be+adj+to+do是常用句式,即名词+be动词+形容词+动词不定式

第一个对,:This question is difficult to answer=It is difficult to answer this question .(be difficult to do sth =have difficult in doing sth)
