A)

(4+x)^2 = 4^2+2.4.x + x^2

= 16 + 8x + x^2

= X^2 + 8x + 16

------------

B)

(3+x)^2 = 3^2+2.3.x+ x^2

= 9+6x+ x^2

= X^2 + 6x + 9

_____________

C)

(5+x)^2 = 5^2 + 2.5.x + x^2

= 25 + 10x + x^2

= x^2 + 10x + 25

________________

D)

(X+6)^2 = x^2 + 2.6.x + 6^2

= x^2 + 12x + 36

____________

E)

(2+x)^2 = 2^2 + 2.2.x + x^2

= 4 + 4x + x^2

= x^2 + 4x + 4

____________

F)

(X+8)^2
