if alpha and beta are the zeros of polynomial f(x) = x^2_5x+k such that alpha--beta = 1, then find k

alpha + beta =-b/a = 5/1

alpha - beta =1

now there are two equations before u,u can solve them by any method to obtain the values of alpha and beta.

alpha =3,beta=2

alpha * beta  = -c/a

put the valu of c and a and get ur answer

1=-k/1

-k=-1

k=1

alpha*beta=c/a

3*2=6

sryyyy@mahek,i forgot to do this in my 1st ans...

hey was it alpha*beta or alpha-beta

medha its alpha -- beta = 1 not alpha*beta
