1.	Let A=⎡⎢⎣−4022x4−30x2⎤⎥⎦B=⎡⎢⎣3b−1⎤⎥⎦C=[263] then the number of integral value (s) 'b' for which Tr(ABC)≤−18∀x∈R is/are
Answer» Let $A = ⎡ ⎢ ⎣ \begin{matrix} - 4 & 0 & 2 2 & x & 4 - 3 & 0 & x^{2} \end{matrix} ⎤ ⎥ ⎦ B = ⎡ ⎢ ⎣ \begin{matrix} 3 b - 1 \end{matrix} ⎤ ⎥ ⎦ C = [\begin{matrix} 2 & 6 & 3 \end{matrix}]$ then the number of integral value (s) 'b' for which $T r (A B C) \leq - 18 \forall x \in R$ is/are
