HELP!! Finding special products of polynomials!!! Need help ASAP!:(?

I can't find anything on the internet that has helped me and I'm really pressed for time to finish my online work, it's polynomials using special products, I need to solve the following problems:

1. (w+x)(w+x)

2. (y-x)(y-x)

3. (wx-y)^2

4. (x+2y)^2

5. (4x^3+7y^3z^4)^2

6. (2x-1/2)^2

7. (0.1x+0.4y)^2

8. (2a^x+1/2b^x)^2

9. (3x^2a -4y^az^3a)^2

10. (x+1)(x-1)

11. (x+y)(x-y)

12. (a+b)(a-2b)

Thank you!!!!

    I'll do a few but don't take my word for it ;)

    Would you try to answer mine if you can?

    1)w^2+x^2... Ect

    I would do all these but I have to leave so I'll give you this method:

    F.O.I.L

    First•first

    outer•outer

    inner•Inner

    Last•Last

    Just use this method for the ones in parentheses like 1,2,10,11,12

    For the rest I'm still not very good at them myself but try to punch it into a online graphing calculator. Sorry if this doesn't help :(
