1) Give an example of factoring using greatest common factor GCF, work the problem using GCF- show all steps.
2) Give an example of factoring trinomials (factor by grouping). Create example and work problem using this method. Show all steps.
3) consider the statement \((x+y)^{2}=x^{2}+y^{2}\) . Choose any nonzero values for x and y. Using your values, show that the statement is not valid. Now use algebra to show that this statement is not valid for x and y in general. Show all of your work.
