What does “Sum and product of roots” actually mean in Quadratic Equations, and why does it matter for JEE?
for ax²+bx+c=0, the roots add to −b/a and multiply to c/a (Vieta's relations).
In simple words: for ax²+bx+c=0, the roots add to −b/a and multiply to c/a (Vieta's relations). Getting Sum and product of roots clear matters because JEE questions on Quadratic Equations usually test this idea directly, not just a formula you memorised.
Key point
Sum and product of roots
Common mistake
dropping the minus sign in −b/a.
Memory tip
sum = −b/a, product = c/a — handy for building equations from roots.
