What is the complete factorization of the polynomial below?
x^3 + 2x^2 + 4x + 8
A. (x - 2)(x + 2i)(x-2i)
B. (x-2)(x + 2i)(x+ 2i)
C. (x + 2)(x + 2i)(x+ 2i)
D. (x + 2)(x + 2i)(x - 2i)

the answer is 99.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

add 8+12 to get a simplified answer of 12r-20
