Question

help and beta are the zeros of polynomial FX = 5 x square - 7 x + 1 then find the value of Alpha / beta + beta / Alpha​

Answer 1

Answer:

alpha+,beta=-(-7/5) and alpha×beta=1/5

alpha/beta+(beta/alpha)

=(alpha^2+beta^2)/(alpha×beta)

={(alpha+beta)^2-2alpha×beta}/(alpha×beta)

={(alpha+beta)^2/(alpha×beta)}-2

=(7/5)^2/(1/5) -2

=49/5 -2

=39/5 Ans
