Question

if alpha and beta are
Zeros of x² - x -1 find the value of 1/alpha+1/ beta
​

Answer 1

Step-by-step explanation:

sum of zeroes=-b/a

alpha + beta = 1

product of zeroes = c/a

alpha * beta = -1

1/alpha + 1/beta=

(beta+alpha)/alpha*beta..................(taking lcm)

1/-1.......................(placing values)

=-1

thus, your answer is -1.....thank you!!
