please solve all the circle ones !!! please please!!​

Answer 1

Answer:

1.g. (x-y)(x-y)

Step-by-step explanation:

g) (x+y)$1) g.  (x+y)^{2}  - 4xy\\=  x^{2} +y^{2}+2xy-4xy\\ =  x^{2} +y^{2}-2xy\\= (x-y)^{2}\\ = (x-y)(x-y)\\\\2)c. 512x^{2} y^{2} - 72\\      =( \sqrt{512} xy - \sqrt{72} )(\sqrt{512} xy + \sqrt{72})\\      =(16\sqrt{2}xy-6\sqrt{2})(16\sqrt{2}xy+6\sqrt{2})\\      = 8(8xy-3)(8xy+3)$
