Thank you for the feedback. I have now changed the questions into gaps to make them less hackable and reworded some of the feedback to be, hopefully, more eloquent and contain less typos.

Thank you again for the feedback, I see what you mean with the statement, and again I am really sorry about the typos. I had changed the statement before but hadn't considered including the simplest form part in it. I am slightly worried that now without any text to preface the questions, the question is looking a bit boring, I'm not sure if there is anyhting I should be writing inbetween questions that you could suggest? 
As for every other question being the same, did you note that the random variable can be both negative and positive. I thought negativity could be a tripping point for someone struggling with expanding brackets, so it would be good to include two versions of each, that way the student wouldn't be put off by a greater variety of the same question? Might it be worth constructing it so that every other example includes negative numbers so they come up less randomly?

Thank you for the feedback, those typos were careless and hopefully they are all sorted now, I have also reworded the question for you.

I hate to disagree but I think that it would be useful for students who are struggling in particular to have the factorise step left in the question to give the student a mid way point. But if there is more logic behind removing the gap, I am happy to take it out.

I've done that simplification
