Question

If a and B are the zeros of the polynomial f(x) = x^2 + x - 2, find the value of (1/alpha-1/beeta)​

Answer 1

Answer:

polynomial f(x) = x^2 + x - 2,

Step-by-step explanation:

• alpha and beta are the zeroes of x^2 + x - 2.
• x^2 + x - 2 = 0
• (X+2) (x- 1) =0
• so x = -2 and x= 1
• alpha is-2 and beta is 1

• Therefore, 1/ alpha - 1/ beta= 1/-2 - 1/1
• -3/2

the answer is-3/2
