U
we have formula ( a - b ) ^2 = a^2+ b^2 - 2ab but during solution of subtraction of roots i.e alfa minus beta you give the formula ((a+b)^2 - 4 a b) ^(1/2) . so, from where this formula is derived sir . a= alfa b = beta

shubham we only know the products of the roots and their sum so we framed the eq. as per the convenience of the required data.If you expand Sir's formulae you will get the same eq as ( a - b ) ^2 = a^2+ b^2 - 2ab.Hope it cleared your doubt
very good explanation
first of all thank you ma'am you are explaning very well and now i am clear with could and should but still i have some problem with would, i know there are lots of people who have queries and its not possible to handle everyone but if you are able to clear my query than this is good for me. and there may be some mistakes in my comment, correct it too.
