Question

10 the polynomial p (x is equal to) a square + 4 + x square + 13 x + 4a is reciprocal of the other then find the value of a​

Answer 1

Answer:

let one zero be α then the other will be 1/α  

clearly from the above step we can see that the product of the roots is 1 so c/a=1

4k/k²+4=1

4k=k²+4

k²-4k+4=0

(k-2)(k-2)

hence k=2
