Question

If α , β are zeroes of x² + 2x + 1 , then 1/α + 1/β = *

-

​

Answer 1

Answer:

1/α + 1/β = -2

Step-by-step explanation:

1/α + 1/β

= (α + β)/αβ

Since,

α + β = - Coefficient of x/Coefficient of x²

=> α + β = - 2/1 = -2

And,

αβ = Constant Term/Coefficient of x²

=> αβ = 1/1 = 1

∴ (α + β)/αβ = -2/1

=> -2 Ans...
