Select each correct answer.

A. 16a^5−20a^3=4^3(4a^2−5)

B. 24a^4+18=6(4a^4+3)

C. 30a^6−24a^2=3a^2(10a^4−8)

D. 12a^3+8a=4(3a^3+2a)

Respuesta :

I’m pretty sure all of them are completely factored.

Answer:

B

Step-by-step explanation:

The only thing that you can factor out of B is 6, while the others are not in simplest form. Answer C can still factor out 2 and answer choice D can still factor out a. Answer choice can still be factored further using difference of squares.
