Fine for quick fire simple factorisations but the problem with these random question generators is there's no progression. These are all just a number outside the bracket with an addition sign between the terms.
This is a starter exercise on 'Factorising'. I use it after we have mastered expanding single brackets. It encourages students to think of different ways in which an expression can be factorised.
I print the two slides of the PPT back to back. Students fill in as many answers as they can in the time given (5-10 mins), so weaker students feel less pressure than they would starting at question 1 from a text book and then working through the questions in order. It can be done individually or in pairs.
When time is up, I get students to come and volunteer their answers on the board, after which we discuss how to ensure that an expression is fully factorised.

This task differentiates learning by giving keener students the chance to show their understanding by doing fewer (but more challenging) problems. For grading students work, I usually give "all the points" or "half the points" for a partially correct solution. You could break it into quarters if you need to be more specific :)
