Question 227764
start by factoring

p^2-9  factors into-->  (p+3)(p-3)

p^2-6p+9 factors into-->  (p-3)(p-3)

To check, first do FOIL.  If they foil to be ur original equations, u have factored correctly.


cross out the terms;  p-3  and  p-3;  remember, if the top AND bottom have same equations, then CROSS.


You are left w/...


p+3 / p-3
