Question

P(x) = x³+3x²-x-2 find
(1) alpha+beta+gama
(2) alpha×beta×gama​

Answer 1

Answer:

for cubic polynomial sum of roots is -b/a

product of roots is -d/a

So 1) is -3/1=-3

2) is -(-2)/1=2

Answer 2

Step-by-step explanation:

(1) alpha+beta+gama = -b/a

(2) alpha×beta×gama = -d/a

here, a=1, b=3, c=-1, d=-2

alpha+beta+gama = -b/a = -3/1 = -3

alpha×beta×gama = -d/a = -(-2)/1

=2/1 = 2
