Solution

$\begin{matrix} T o f i n d t h e v a l u e o f x, s i m p l i f y i n g ↓ \Rightarrow x (x - 3) + 2 \Rightarrow x^{2} - (2 x + x) + 2 \Rightarrow x^{2} - 2 x - x + 2 \Rightarrow x (x - 2) - ------ - - 1 (x - 2) - ------ - \Rightarrow (x - 2) (x - 1) \Rightarrow (2 - 2) (2 - 1) [∵ g i v e n x = 2] \Rightarrow 0 \times 1 \Rightarrow 0 A n s . \end{matrix}$
