Answer 2

Answer:

Step-by-step explanation:-

Given that, f(x) = x^2-x-4 .

a=1,b=-1,c=-4.

Sum of zeroes = α+β = -b/a = 1/1 = 1.

Product of zeroes =αβ= c/a = -4/1 = -4.

1/α+1/β-αβ = {β+α-(αβ)^2}/αβ

= {α+β-(αβ)^2}/αβ

= (1 - (-4)^2)/-4

= (1 - 16)/-4

= -15/-4

= 15/4

So, option A is the right answer....
