Question

if one of zeros of polynomial p(x): x2-8x+k is seven times of other then find the value of k

Answer 1

let on zero be x
so other zero is 7x
sum of zeroes is 8/2 =4
x+7x=4
8x=4
x=1/2
7x=7/2
k/2=1/2.7/2
k/2=7/4
k=7/2

Answer 2

if one zero seven times the other then the value of k for given polynomial is 7
