3 + 7x.​

Answer 1

7 + 3x will be a factor of 3x3 + 7x only if 7 + 3x divides 3x3 + 7x leaving no remainder. ∴ 7 + 3x is not a factor of 3x3 + 7x.

Step-by-step explanation:

Answer 2

Answer:

Let us divide (3x3 + 7x) by (7 + 3x). If the remainder obtained is 0, then 7 + 3x will be a factor of 3x3 + 7x. By long division, As the remainder is not zero, therefore, 7 + 3x is not a factor of 3x3 + 7x.
