2y^3  -  5y  + 5/2

       --------------------------------------------------

2y - 5) 4y⁴ - 10y³ - 10y² + 30y - 15

4y^4 - 10y^3  

    -------------------------------

-10y^2  +  30y

-10y^2  +  25y          

--------------------------------

5y  -   15

5y  -  25/2                                                   -----------------------------------              

-5/2

hence (2y - 5) is not a factor of 4y⁴ - 10y³ - 10y² + 30

Step-by-step explanation:

Answer 2

Answer:

2 - 5 is -3. This is not a factor of 4.

4 + 7 is 11 which is not a factor of 4.

2 + 15 is 17 which is not a factor of 4.

Hence, all the numbers are not factors of 4.
