D. x2 + 6x + 8

Answer 1

x*x =
x*2 =
4*x =
4*2 =
It's just using FOIL. Multiply those 4 individual problems and then add up the results : )

Answer 2

(x + 4)(x + 2)
(x+4)(x+2)=x*x+x*2+4*x+4*2
(x+4)(x+2)=x^2+6x+8

Answer 3

\[(x+4)(x+2)=x(x+2)+4(x+2)=x ^{2}+2x+4x+8=x ^{2}+6x+8\]

Answer 4

So the answer is option D
