Question

if alpha and beta are the zeros of the polynomial x square - 2 x minus 8 then find the values of Alpha by beta + beta by Alpha​

Answer 1

Answer:

GIVEN, α and β are the zeroes

x² - 2 x - 8

α+β = -b/a

       =  2  

αβ = -8

⇒ α/β + β/α

   (α+β)/αβ

after substituting the values..

  = 2/-8

  = 1/-4
