Answer 2

▬▬▬▬▬▬▬▬▬▬▬▬▬

As it's given zeroes of polynomial is 2.

We know that that if α is a zero of the polynomial p(x), then p(α) = 0

Now, substituting x = 2 in x² + 3x + p or p(x).

⇒2² + 3(2) + p = 0

⇒4 + 3 × 2 + p = 0

⇒4 + 6 + p = 0

⇒10 + p = 0

⇒p = 0 - 10

⇒p = - 10

∴ The Required value of p is - 10.
