...Figure it out yourself. We aren't here to give you answers so don't ask questions right from your tests. This is just plugging stuff in and if that is not something you are comfortable with, you need to go study more or ask how to factor properly. If we use this site to cheat (which is what you are asking us to do since you are just asking for answer) then we don't learn and there is a chance the teacher will find out.
