1. Answer:

   2(2)+3(2)+p=0

   so 4+6+p=0

   10+p=0

   p=_10

2. Answer:

   As 2 is the zero of the polynomial.

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

   Substituting x = 2 in x2 + 3x + p,

   ⇒ 22 + 3(2) + p = 0

   ⇒ 4 + 6 + p = 0

   ⇒ 10 + p = 0

   ⇒ p = -10

   Hope it helps ♡
