use formula : α  β =  (sqrt(D)/a)  with D=b^24ac

oh yeah... forgot to put  without finding the roots So like using αβ = c/a and α+β=b/a

right, but ur problem to find value of α  β?

apple_pi Group TitleBest ResponseYou've already chosen the best response.0
yes. find α  β

we know that general form of a quadratic equation is ax^2+bx+c=0 so, we can find α  β with formula : α  β = abs(sqrt(D)/a)

You can always count on finding the roots and assuming them as \(\alpha, \beta\).

@ParthKohli, without finding roots

RadEn Group TitleBest ResponseYou've already chosen the best response.0
yea, right to.. but should use absolut sign because not known α > β or α < β
