Option A 12x^4 + 12x^3 + 26x^2 + 8x + 12

Step-by-step explanation:

1) Find area of Shape A

(3x^2 + 2) (7x^2 + 4x + 8)

With distribution method, you get

21x^4 + 12x^3 + 38x^2 + 8x + 16

2) Find area of shape B

(3x^2 + 2) (3x^2 + 2)

With distribution method, you get

9x^4 + 12x^2 + 4

3) Subtract area of Shape B from Shape A

21x^4 + 12x^3 + 38x^2 + 8x + 16

-9x^4                 -12x^2            -4

12x^4 + 12x^3 + 26x^2 + 8x + 12

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.
