Question

plz tell me how this came..
this firat line ​

Answer 1

Let consider the both polynomial as alpha and beta

So that eq came because

F(x)=x^2+px+45

Put

Here

(Alpha-beta)^2-4alpha beta =45

Because

Sum=alpha +beta

And polynomial =-p

So we take these equation

Hope you like my ans

Answer 2

Explanation:

= F (x) = x^2 + Px + 45

Now , Alpha Beta ^2 - 4 Alpha Beta = 45

Polynomial = P
