SOLUTION:
Step 1:
In this question, we are given the following:
Expressing:
[tex]12\text{ x - 9x - 4x + 3}[/tex]Step 2:
The details of the solution are as follows:
[tex]\begin{gathered} 12\text{ x -9x - 4 x + 3} \\ \text{= -x + 3} \\ =\text{ -\lparen x -3\rparen } \end{gathered}[/tex]CONCLUSION:
The final answer in factored form =
[tex]-(x-3)[/tex]
