Question

if one zero of polynomial 3x2-8x-(2k+1) is seven times the other find both zeroes and value of k ...this is question of class 10th ..plz try to solve it as soon as possible it's urgent.​i will definitely mark u as brainlist.

Answer 1

Answer:

Let the zero of polynomial be α,7α

sum of roots is given by 

a−b=38

8α=38

α=31

product of roots $

ac=2k+1

7α2=2k+1

97=2k+1

2k=9−2

k=9−1
