Question

if α and β are the zeroes of polynomial f(x) = x2+x+1 , find 1/ α + 1/ β​

Answer 1

Answer:

Answer

Correct option is

C

−1

f(x)=x

2

+x+1

a=1

b=1

c=1

∵α and β are the zeroes of above polynomial.

∴ Sum of roots =

a

−b

⇒α+β=

1

−1

⇒α+β=−1⟶(1)

Product of roots =

a

c

⇒αβ=

1

1

⇒αβ=1⟶(2)

∴
