Answer 1

Answer:

No, it is not the factor

Hope it helps you

Answer 2

Answer:

It is not a factor.

Step-by-step explanation:

p(x) = 3x^3 + 7x

7+3x=0

3x= -7

X= -7/3

p(-7/3) = 3(-7/3)^3 + 7(-7/3)

= 3×-343/27 + (-49/3)

= -343/9 + (-49/3)

LCM = 9

= (-343 - 147)/9

= -490/9

Therefore 7+3x is not a factor of 3x^3+7x.
