Question

formula for alpha square plus beta square

Answer 1

Hello friend your answer is
The Formula of α²+β²=
(α+β)²-2αβ

Answer 2

Hey!

Thik is a Abhiranjan raj helping for you.

Suppose a is alpha and B is beta.

then.a^2+B^2

=(a+B)^2-2aB

we know that sum of alpha and beta is -b/a

and know that product of alpha beta is =c/a
so,

=(a+B)^2-2aB

=(-b/a)^2-2(c/a)

=b^2/a^2-2c/a

=b^2-2ac/a^2.

Hope it helps you
