Question

How to find the number of real and complex root in a polynomial?

Answer 1

First find degree of polynomial

that is number of roots

complex roots occur in pairs

for example

if degree =5

complex roots 0 and real root 5

complex roots 2 and real root 3

or

complex roots 4 and real root 1

but we can not conform

anyway we conform atleast 1 real root

any doubt
