Question

please answer the questions​

Answer 1

Answer:

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

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

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

d) (x+y+z)^2 = x^2+y^2+z^2+2xy+2yz+2zx

Answer 2

Answer:

Your answer is

(a) (x‐y)^2 = x^2 ‐2xy +y^2

(b) (x^2‐y^2) = (x‐y)(x+y)

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

(d) (x+y+z)^2 = x^2+y^2+z^2+2xy+2yz+2zx
