SOLUTION: Hello! I am working on my Foiling, and I wish to know if I worked it out correctly. (7x + 4y)^2 = (7x + 4y)(7x + 4y) = 49x^2 + 28xy + 28xy + 16y^2 = 49x^2 + 56xy + 16y^2

Question 466634: Hello! I am working on my Foiling, and I wish to know if I worked it out correctly.
(7x + 4y)^2
= (7x + 4y)(7x + 4y)
= 49x^2 + 28xy + 28xy + 16y^2
= 49x^2 + 56xy + 16y^2
Thanks
