Question

algebra 2 question!! Simplify the rational expression & state any restrictions on the variable?

Answer 1

\[\ \frac{ p^2-4p-32 }{ p+4 }\]

Answer 2

Why must there be any restrictions on the variable?

Answer 3

First you have to simplify the numberator, which is p^2 - 4p - 32
You have to do reverse foil on this.

If I said you can simplify that to (p-8)(p-4), would that make sense to you?

Answer 4

@skullpatrol To prevent division by zero, perhaps?

Answer 5

Most definitely @ChristopherToni

Answer 6

, I may need a refresher on this but I believe there is a hole at p=-4
