For this case we must find the product of the following expression:
[tex]6 (x ^ 2-1) * \frac {6 (x-1)} {6 (x + 1)}[/tex]
We can rewrite [tex]x ^ 2-1[/tex] as:
[tex](x + 1) (x-1)[/tex], then:
[tex]6 (x + 1) (x-1) * \frac {6 (x-1)} {6 (x + 1)} =[/tex]
Canceling similar terms of the numerator and denominator:
[tex](x-1) * 6 (x-1) =\\6 (x-1) ^ 2[/tex]
ANswer:
[tex]6 (x-1) ^ 2[/tex]
