Answer 10

@Tennis5518

This factorization --->9(a^2 + b)(a^2 - b) for the given problem "Factor 9a^4 - b^2"
is incorrect. If you multiply 9(a^2 + b)(a^2 - b), you get 9a^4 - 9b^2 which is not the original problem.

Answer 11

Factor with the difference of two squares format:

9a^4 - b^2 = (3a^2 + b) * (3a^2 - b)

Answer 12

Oh so it's (3a^2 - b)
rather than 9(a^2 + b)(a^2 - b) @Directrix

Answer 13

All of this is the correct answer: (3a^2 + b) * (3a^2 - b)

Answer 14

>>Oh so it's (3a^2 - b) Wrong

Answer 15

Correct Answer: (3a^2 + b) * (3a^2 - b)
