2(x + 4)(x + 4)
2(x + 4)(x − 4)

Answer 1

2(x + 4)(x − 4)

Answer 2

thanks... how do you figure that out?

Answer 3

ok first b/c u have 2 in common so put the two out

Answer 4

then u get 2(x^2-16)

Answer 5

then 2(x-4)(x+4)

Answer 6

lol sry ik im not gd at explaining..

Answer 7

ok... i think i get it now... thanks!!! :)

Answer 8

2 is common so take it out
\[2(x^2-16)\]
\[x^2-y^2=(x+y)(x-y)\]
so,\[2[(x)^2-(4)^2]=2(x+4)(x-4)\]
