Question

if one zero of f(X) = (b^2+4)x^2 + 13x + 8 is reciprocal of the other then b = ?

Answer 1

Answer:

Hey mate here's ur answer...

Step-by-step explanation:

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

4b/b²+4=1

4b=b²+4

b²-4b+4=0

(b-2)(b-2)

hence b=2
