Question

How do you simplify and find the restrictions for `(x-1)/( (x-3)(x+1))`?

Answer 1

`x!=3,-1`

Explanation:

`"the rational function is already in simplest form"`

`"the restrictions are any values of x that would make the"`
`"rational function undefined"`

`"equating the denominator to zero and solving gives the"`
`"values that x cannot be"`

`"solve "(x-3)(x+1)=0`

`rArrx=3,x=-1larrcolor(red)"are restricted values"`
