Question

(a) Find the value of k, if one of the zero of the quadratic polynomial x² + 3x +k is 2.
(b) Find the number of zeroes of the polynomial from the graph.​

Answer 1

Answer:

a) k = -10

b) The number of zeroes of a polynomial depends on the number of times it cuts the x - axis.

Step-by-step explanation:

a) p(x) = x² + 3x + k

   p(2) = 4 + 6 + k = 0

Thus, k = -10
