Answer:

4 x^2 + 4 x y + y^2

Step-by-step explanation:

Expand the following:

(2 x + y)^2

(2 x + y) (2 x + y) = (2 x) (2 x) + (2 x) (y) + (y) (2 x) + (y) (y):

2×2 x x + 2 x y + 2 y x + y y

2 x×2 x = 2×2 x^2:

2×2 x^2 + 2 x y + 2 y x + y y

2×2 = 4:

4 x^2 + 2 x y + 2 y x + y y

y y = y^2:

4 x^2 + 2 x y + 2 y x + y^2

x y 2 + y x 2 = 4 x y:

Answer: 4 x^2 + 4 x y + y^2
