Answer 2

I can help you with these algebra problems. Here are the detailed solutions:

1) (3-y)(3+y) = 9 - y^2 This is an example of the difference of squares formula: (a-b)(a+b) = a^2 - b^2. In this case, a = 3 and b = y, so we get (3-y)(3+y) = 3^2 - y^2 = 9 - y^2.

2) (c-p)(c+p) = c^2 - p^2 This is another example of the difference of squares formula: (a-b)(a+b) = a^2 - b^2. In this case, a = c and b = p, so we get (c-p)(c+p) = c^2 - p^2.

3) (3b-1)(3b+1) = 9b^2 - 1 This is yet another example of the difference of squares formula: (a-b)(a+b) = a^2 - b^2. In this case, a = 3b and b = 1, so we get (3b-1)(3b+1) = (3b)^2 - 1^2 = 9b^2 - 1.

4) (a+2b)(a-2b) = a^2 - 4b^2 This is the last example of the difference of squares formula: (a-b)(a+b) = a^2 - b^2. In this case, a = a and b = 2b, so we get (a+2b)(a-2b) = a^2 - (2b)^2 = a^2 - 4b^2.

I hope this helps you understand how to use the difference of squares formula. If you want to learn more about algebra, you can check out some of the web search results I found for you . Have a nice day!
