Question

If alpha and beta are the zeros of the polynomial p(x) is equals to X square + X - 2 find the value of [one upon Alpha minus one upon beta]

Answer 1

x^+X-2

x^+2x-x-2

x(x+2) -1(x+2)

(x+2) (x-1) =0

alpha=-2 and beta=1.

one upon alpha-one upon beta.

-1/2-1/1

= -1/2 -2/2

-3/2 is answer.
