Question

if one zero of the polynomial x²+3x+k is reciprocal of the other find the value of k​

Answer 1

Answer:

Let the given quadratic polynomial be p(x) = x2 + 3x + k Given one of the zero of the quadratic polynomial is 2. Hence p(2) = 0 Put x = 2 in p(x), we get p(2) = 22 + 3(2) + k ⇒ 0 = 4 + 6 + k ⇒ 0 = 10 + k ∴ k = – 10

Answer 2
