Question

if alpha and beta are roots of quadratic eq x^2-3=0,then 1 upon alpha + 1 upon beta​

Answer 1

Answer:

here u go

Step-by-step explanation:

1/α + 1/β =

(1/α)×(β/β) + (1/β)×(α/α)

(β/αβ) + (α/αβ)

(β+α)/(αβ) ---- OR --- (α+β)/(αβ)

(α+β)/(αβ) can be further written as

(-b/a)/(c/a)

where b = coefficient of x

where c = coefficient of xⁿ (n=0)

therefore xⁿ= 1
