Answer 1

Answer:

p(x)= x^2-5x+4

sum of zero ;

alpha +beta = -b/a = 5.

product of zero;

alpha ×beta = c/a= 4.

so acc to question,

1/alpha +1/beta -2alpha beta.

put value of alpha ×beta .

1/alpha +1/beta -2(4).

[beta +alpha /alpha beta ] -8.

( 5/4) - 8.

take LCM.

5-32/4.

27/4.

I hope its correct..

my calculation part may be wrong but method is correct
