multiply by the formula or vice versa - to determine the polynomial multiplied.

1. (10-3y)^{2}= 2. (m+3) (m+3) =

3. (5x4y^{2})^{2}=

4. (m+n)^{2}=

5. (s-t)^{2}=

6. (2a+5)^{2}=

7. (-a+3c)^{2}=

8. (-5x-3y)^{2}=

9. c^{2}- 2cd + d^{2}=

10. (10a+2)^{2}=

11. (3m^{2}+4n) (3m + 4n) =

12. (5-x) (5-x) =

13. (x-y)^{2}=

14. (p+3)^{2}=

15. (4-3b)^{2}=

16. (-2a-5b)^{2}=

17. (-4+3m)^{2}=

18. m^{2}+ 2mn + n^{2}=
