its wrong as this polynomial zero are not 2 alpha and 2 beta
Then
The question was to find the polynomial with roots 2alpha by beta and 2 beta by alpha
yes i know but you can check as my new polynomial satifies the condition you can check that .......
No it won’t. The roots of x square minus 1 are 1 and -1. So 2alpha by beta and 2 beta by alpha both are -2. But for your polynomial roots are 2 and -2
