Question

if alpha and beta are the zeros of the x squared minus 4 x + 3 find the values of Alpha 4 beta Cube + aplha cube + beta 4

Answer 1

x sq -4x +3=0

here a=1,b=-4 ,c=3

alpha + bita = -b/a
= 4
alpha.bits=c/a
= 3

Now alpha 4 beta cube + alpha cube beta 4
so alpha cube .beta cube(alpha + bita)[jus taking common]

Now (apha.beta)cube (alpha + bita)
(3)cube.(4)
27.4
= 108 Ans
