Question

Q).. If k is the ratio of the zeros of the polynomial 3 x²- 7 x + 2 then the value of 1/√2(k+1/k)½ is​

Answer 1

Answer:

Given −3 is the zero of the polynomial (k−1)x2+kx+1

So −3 must satisfy the equation (k−1)x2+kx+1=0

⟹(k−1)(−3)2+k(−3)+1=0

⟹9(k−1)−3k+1=0

⟹9k−9−3k+1=0

⟹6k=8

⟹k=34
