Question

3. Check whether 7 + 3x is a factor of 3x cube
+ 7x.​

Answer 1

Answer:

No

Step-by-step explanation:

This can be checked by the method of Remainder theorem

If 7 +3x is a factor of 3x^3 +7x then Remainder will be equal to zero

and 7 +3x =0 ---> x=-7/3

Put this value in 3x^3 +7x

You will get -490/9

Thus this is not equals to zero so

Its not a factor
