​

Answer 1

Step-by-step explanation:

X+Y= 3

The value of X and Y can be multiples, Like

X= 0, Y= 3

X=1, Y= 2

X= 3, Y= 0

Answer 2

Answer:

(x+y)² =(x+y) (x+y)

(x+y)² =(x+y) (x+y) = xx + xy + xy + y = x² + 2xy + y²

(x+y)3 = (x² + 2xy + y²) (x+y)

(x+y)3 = (x² + 2xy + y²) (x+y)

= x2x +2xxy + xy2 + x2y + 2xyy + y2y

= x3 + 3x2y+ 3xy2 + y3
