Question

I need help getting the answer

Answer 1

Answer:

b^2-16 , 16a^2-4

Step-by-step explanation:

m^2+36 is not a difference its a sum so that is automatically ruled out

3x^2-4, 3 isn't a squared number so it can not be used

b^2-16 , is a difference of squares - (b-4)(b+4)

16a^2-4, is also a difference of squares - (4a-2)(4a+2)
