CBSE Class 10 Answered
There are so many identities related to alpha and beta .i.e zeroes and coefficients please tell me the identities which can come in exam and are very important ?

Expert Answer
The most important one is that for a quadratic equation, ax^2 + bx+c = 0
sum of roots (alpha+beta) = -b/a
and product of roots (alpha*beta) = c/a.
Most of the other identities for quadratic equation can derived from these 2 equations itself.
