We will have two factors, one for the columns and the other for the rows.
For the columns we have x-1-1-1 = x-3.
For the rows we have x+x+1+1 = 2x+2.
If we multiply both factors and apply the distributive property we obtain:
[tex]\begin{gathered} (x-3)(2x+2) \\ x*2x-3*2x+x*2-3*2 \\ 2x^2-6x+2x-6 \\ 2x^2-4x-6 \end{gathered}[/tex]
Answer: 2x² - 4x - 6
