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
