Question

How do you simplify `\frac { v - 2} { v ^ { 2} - 4v + 4}`?

Answer 1

`1/(v-2)`

Explanation:

We can factor the denominator - let's see if that helps:

`(v-2)/(v^2-4v+4)`

`(v-2)/((v-2)^2)`

We can now cancel the numerator against one of the `(v-2)` terms in the denominator:

`cancel(v-2)/((v-2)^cancel2)`

`1/(v-2)`
