Question

If & and B are the zeroes of a quadratic polynomial p(x)=x^2+x-2,find the value of 1/alpha-1/beta

​

Answer 1

Answer:

Step-by-step explanation:

/alpha - 1/beta = 1/0 - 1/0

= infinity - infinity

which is not defined

if incase

"If alpha and beta are the solutions of the polynomial"

x^2 + x - 2 =0

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

=> x= -2 or x =1

therefore (alpha,beta) = (1,-2) or (-2,1)

1/alpha - 1/beta = +(3/2) or -(3/2)
