Rewrite x^2+9 as a product using complex numbers and the polynomial identity below.

a. (x+3)(x-3)
b. (x+3i)(x-3i)
c. (3x)(3i)
d. (x+9i)(x-9i)

I'm not sure if it's b or d, if I'm on the right path. Please help? Thanks

9 = 3^2, so it's (b)

which you could have verified by actually doing the multiplication, guy.
