1.	Let a, b, c be the sides of the triangle. No two of them are equal and λ∈R. If the roots of the equation x2+2(a+b+c)x+3λ(ab+bc+ca)=0 are real then :
Answer» Let a, b, c be the sides of the triangle. No two of them are equal and $λ \in R$ . If the roots of the equation $x^{2} + 2 (a + b + c) x + 3 λ (a b + b c + c a) = 0$ are real then :
