Question

If alpha and beta are the zeroes of the polynomial ax^2+bx+c, find alpha/beta+beta/alpha.​

Answer 1

Step-by-step explanation:

alpha/ beta + beta/ alpha=

(alpha square + beta square)/ alphabeta=

{(alpha + beta) whole square - 2 alphabeta}/ alphabeta=

put values of alpha+ beta and alphabet,

{(-b/a)^2 - 2(c/a)}/ c/a =

(b^2- 2ac)/a
