Answer 1

Step-by-step explanation:

In the first part take LCM of alpha and beta to make it alpha²+beta²/alpha×beta

We know that alpha×beta = 1(in this particular case)

So, we have to find the value of alpha²+beta² whose formula is (alpha+beta)²-2×alpha×beta

so it will be (-1)²-2 that is 1-2=-1
