CBSE Class 10 Answered
if alpha and bita are the zeroes of a quadratic polynomial X^2+X-2 then find the value of(1/alpha -1/bita)

Hint
x2 + x - 2
x2 + 2x - x - 2
x(x + 2) - (x + 2)
(x - 1) (x + 2)
x = 1, x = -2
So these are the possible zeroes.
Now simplify

Therefore the possible values are
(-3/2) or (3/2)
Note - a similar problem is solved here.
