in this case its easy to divide each part by 4a:
48a^3 / 4a = 12a^2 (divide the 48 by 4 and divide the a^3 by a)
32a^2 / 4a = 8a
16a / 4a = 4
D. 12a^2 + 8a + 4

48a^3 + 32a^2 + 16a
= 4a( 12a^2 + 8a + 4)
The answer is therefore the factor in brackets.
Answer D.

48a^3+32a^2+16a divided by 4a
=48a^3/4a +32a^2/4a +16a/4a
=12a^2+8a+4
Hence D is the correct answer

= 16a.(3a² + 2a + 1) / 4a
= 4.(3a² + 2a + 1)
= 12a² + 8a + 4
