9a4-b2=36a-2b=2(18-b) But if you meant 9a^4-b^2 it is not possible to factor
Assuming the missing sign is "minus" then you have the difference between two squares. This is solved as (x + y)(x - y). In your example x = 4a and y = 2b so the factorisation is (4a + 2b)(4a - 2b) or more completely: (4)(2a + b)(2a - b).
