Question

Is alpha and beta are the zeros of a polynomial f(x) = x2 + 5x + 8 then 1/alpha and 1/beta =

Answer 1

Answer:

f(x) = x2 + 5x + 8

here,

alpha and beta are the zeros

f(1/alpha)=1/alpha+5*1/alpha+8

f(1/0)=1/0+5*1/0+8

f(infinity)=infinity

f(1/beta)=1/beta+5*1/beta+8

f(1/0)=1/0+5*1/0+8

f(infinity)=infinity
