Question

X + Y the whole square + x minus y the whole square​

Answer 1

(x+y)²-(x-y)²=(x²+2xy+y²)-(x²- 2xy+y²)=x²+2xy+y²-x²+2xy-y²=2xy+2xy=4xyThis is the answer i guess.

Answer 2

Answer:

Step-by-step explanation:

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

                              = 2x^2 + 2y^2

                              = 2(x^2 + y^2)
