Question

Answer the following question​

Answer 1

Answer:

(-b/a)

Step-by-step explanation:

Cubic equation is in form x³-(a+b+c)x²+(ab+bc+ca)x-abc

Here a,b,c are alpha, beta and gamma.

on comparing, dividing by a, we have:

x³+(b/a)x²+(c/a)x+(d/a)

Here a,b,c are from question.

now we get -b/a by comparing them.
