B. 5h2, 16
C. 5h3, 4
D. h2, h

Answer 1

Find the GCF of the first two terms and the GCF of the last two terms of the polynomial.

5h3 + 20h2 + 4h + 16
Answer is A. 5h2,4

Answer 2

Answer: A.
`5h^2,4`

Explanation:

The given polynomial :
`5h^3 + 20h^2 + 4h + 16`

Here, the first two terms =
`5h^3 \text{ and }20h^2`

`5h^3=5* h* h* h\\\\20h^2=4*5* h* h`

Then, the greatest common factor of first two terms (GCF)=
`5*h* h=5h^2`

The last two terms :
`4h\text{ and }16`

`4h=4* h\\\\16=4*4`

Then, the greatest common factor of last two terms (GCF)=
`4`
