(a) Both Assertion and Reason are true and Reason is a correct explanation of Assertion.
Assertion:
Let:
Now,
By the remainder theorem, we know that when
Now, we have:
Hence, Assertion is true.
Reason: If p(x) is divided by (x − a), then the remainder is p(a).
The given statement is true.
Therefore, both Assertion and Reason are true and Reason is a correct explanation of Assertion.
