Question

cubic polynomial x³+3x²-x-2 find the value of alpha+beta+gamma,alpha beta+beta gamma+ gamma alpha=alpha beta gamma​

Answer 1

Alpha+Beta+Gama = -b/a

= -3/1

= -3

alpha beta+beta gamma+gamma alpha = c/a

= -1/1

= -1

alpha beta gamma = -d/a

= -(-2)/1

=2

Tip ---- take polynomial as ( ax^3+bx^2+cx+d)
