Question

if alpha and beta are zeros x^2 + x -2 find the value of 1 upon alpha - 1 upon beta​

Answer 1

Answer:

3/2 or -3/2

Step-by-step explanation:

x^2 +2x - x - 2

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

(x-1)(x+2)

Therefore,

alpha = 1

and beta = -2

1/alpha - 1/beta

1/1 - 1/(-2)

1+1/2

=>3/2

or if alpha = -2

and beta = 1

then,

1/(-2) - 1/1 = -3/2
