Ricardo is factoring the polynomial, which has four terms. 5x3 + 20x2 + 2x + 8 5x2(x + 4) + 2(x + 4) which is the completely factored form of his polynomial?
a. 5x2(x + 4)
b. 7x2 (x + 4)
c. (7x2 + 2) (x + 4)
d. (5x2 + 2) (x + 4)

Option D is correct

Step-by-step explanation:

Ricardo is factoring the polynomial which has four terms.

.

Factor by grouping,

If all of the terms in a polynomial contain one or more identical factors, combine those similar factor into one monomial, called Greatest Common Divisor(GCD).

In polynomial i.e there is factor (x+4) that's greatest common divisor.

Finally, writing factored expression as the product of the GCD and the remaining terms,

Therefore, Completely Factored form of his polynomial is,
