3x³+7x
→7+3x is a factor of the given polynomial.
7+3x = 0
3x = -7
x = -7/3
★3(-7/3)³+7(-7/3)
→ 3(-243/27)-49/3
→ -243/9 - 49/3
→ -81/3-49/3
→ (-81-49)/3
→ -130/3
As the remainder is not equal to zero, 7+3x is not a factor of the given polynomial 3x³+7x.
Hope it helps…

7+3x=0
x=-7/3
putting x on p(x)
(-3*(-7/3)^3)+(7*-7/3) is not equal to 0
so 7+3x is not a factor.
