Alfa³ + Beta³
__________
Alfa × Beta
=
( Alfa + Beta )³ - 3Alfa×Beta{ Alfa + Beta}
_____________________________
Alfa + Beta
=
{Alaf+Beta}{ (Alfa+Beta)² - 3Alfa × Beta}
______________________________
{Alfa + Beta}
=
{ (Alfa + Beta)² - 3Alfa × Beta }

Thank you
ur vlcm.
If alpha+beta=-5/4 at alpha+beta=1/4 wht may be the ans plz tell
What we have to find?
plz
tell me the question properly
Alpha+beta=-5/4 and alphaxbeta=1/4, now have to find alpha square/beta+beta square/alpha
Alfa² / Beta + Beta² / Alfa = ( Alfa + Beta )² - 3 Alfa × Beta = ( -5/4)² - 3 ( 1/4 ) = 25/16 - 3/4 = ( 25 - 12 ) / 16 = 13/16
