When and If is divided by , the remainder is 12. Option (D) is correct and option (E) is correct.

Further Explanation:

Explanation:

If division of a polynomial by a binomial result in a remainder of zero means that the binomial is a factor of polynomial.

The synthetic division can be expressed as follows,

The last entry of the synthetic division tells us about remainder and the last entry of the synthetic division is . Therefore, the remainder of the synthetic division is .

When and If is divided by , the remainder is 12. Option (D) is correct and option (E) is correct.
