3

Restrictions

$y!=+-1$

$(3(y^2) - 3) / ((y^2) - 1)$

Factor the numerator using the distributive property:

$=(3((y^2)-1))/((y^2) - 1)$

cancel common factors:

$=(3(cancel((y^2)-1)))/(cancel((y^2) - 1))$

$=3$

Restrictions:

$(y^2) - 1 !=0$

$y^2 != 1$

$y != +-sqrt1$

$y!=+-1$

How do you simplify (3(y^2) - 3) / ((y^2) - 1)(3(y^2) - 3) / ((y^2) - 1) and what are the restrictions?
