Greetings!
Solve for the missing factor: [tex](x)[/tex]
[tex]n(n-3)+2(n-3)=x(n-3)[/tex]
Divide both sides by [tex](n-3)[/tex]:
[tex] \frac{n(n-3)}{(n-3)} + \frac{2(n-3)}{(n-3)}= \frac{x(n-3)}{(n-3)} [/tex]
Cancel Common Factors:
[tex]n+2=x[/tex]
The Missing Factor is:
[tex]\boxed{n+2}[/tex]
I hope this helped!
