Given ax2 + bx +c ≥0 , bx2+cx+a≥0 , cx2+ax+b≥0 where a≠b≠c – InterviewSolution

1.	Given ax2 + bx +c ≥0 , bx2+cx+a≥0 , cx2+ax+b≥0 where a≠b≠c and a,b,cϵR . Now a2+b2+c2ab+bc+ca cannot take the value(s)
Answer» Given $a x^{2}$ $+$ $b x$ $+ c$ $\geq 0$ , $b x^{2} + c x + a \geq 0$ , $c x^{2} + a x + b \geq 0$ where $a \neq b \neq c$ and $a, b, c ϵ R$ . Now $\frac{a^{2} + b^{2} + c^{2}}{a b + b c + c a}$ cannot take the value(s)
