Question

If $x=2$, then $(x-1)(2x-3)=$?

Answer 1

Find the value of the given expression

Given, $(x-1)(2x-3)$

Substituting $x=2$ in the given equation, we get,

$(x-1)(2x-3)$
$$\begin{gathered} =(2-1)\left\{2\left(2\right)-3\right\} \\ =\left(1\right)\left\{4-3\right\} \\ =\left(1\right)\left\{1\right\} \\ =1 \end{gathered}$$
Hence, the value of $(x-1)(2x-3)$ at $x=2$ is $1$.
