Question

If alpha and beta are the zeroes of the quadratic polynomial p(x)=6x²+x-2 then find the value of alpha-beta, alpha²+beta², 1/alpha+1/beta alpha beta²+alpha²beta

Answer 1

Answer:

solutions:-

(1) α-β = √29/6

(2) α²+β² = 25/36

(3) 1/α+1/β = 2

(4)αβ²+α²β = 1/18

Explain:-

p(x)=6x²+x-2

α+β = -1/6 αβ = -1/3
