Margie, when you have answered these the best you can, please re-post and someone here will be happy to give you suggestions and let you know where you need to make corrections. Please keep in mind that we don't do students' homework for them.
hint:
these are all quadratic equations and all of them factor.
So expand if necessary, bring all the terms to the left side and set them equal to zero.
Factor them and from the factors determine the solutions.
I am sure they have shown you how to do that.
