Question

If a B are the zeroes of p(x)=2x*x+x-1
then 1/alfa +1/bita​

Answer 1

Step-by-step explanation:

there !! p(x) = x² + x - 1 a = 1 b = 1 c = -1 α and β are zeros of p(x) α + β = -1 [α + β = -b/a ] αβ = -1 [αβ = c/a ] To find :-

Answer 2

Answer:

answer is 1

Step-by-step explanation:

Alpha and Beta are the zeroes of quadratic equation

Then, Alpha+Beta=  -1/2

           Alpha.Beta=-1/2

Then,  1/alpha + 1/beta

 Taking L.C.M

=(alpha+beta)/alpha.beta

put the values of (alpha+beta) and (alpha.beta)

=-1/2/-1/2

1/alpha + 1/beta=1
