Question

Find a polynomial whose zeros are 2,1 and -1 .what is its degree?

Answer 1

Answer:

let alpha =2

beta=1

gama=(-1)

sum of zeros =2+1+(-1)=2

product of zeros takes two at a time=[ {2×1}+{1×(-1)}+{(-1)×2}]

=2+(-1)+(-2)

=-1

product of zeros =2×1×(-1)

=(-2)

so required p(x)= x3-(2)x2+(-1)x -(-2)

= x3-2x2-x+2

Degree =3
