(x-y)^2

(x-2y)^2

(a+b)^2

(a^2+5b)^2

(X+3y)(x-3y)

(x^2+3y^2)(x^2-3y^2)

4ab(a+b)^3

Answer 1

wdf ic ant do tht lol

Answer 2

x^2-y^2

x^2-4y^2

a^2+b^2

a^4+25b^2

x^2-9y^2

x^4-9y^4

4a^4b+4ab^4

Answer 3

(x-y)^2= x^2-2xy+y^2

(x-2y)^2=x^2-4xy+4y^2

(a+b)^2=a^2+2ab+b^2

(a^2+5b)=a^4+10ba^2+25b^2

(x+3y)(x-3y)=x^2-9y^2

(x^2+3y^2)(x^2-3y^2)=x^4-9y^4

4ab(a+b)^3=4ab(a^3+2a^2b+2b^2a+ab^2+ba...
