Answer:
- a.

- b.

Step-by-step explanation:
a. 



b. 







The answer is c. Because insert x=2 into the equation and 2x2=4-3=1 sooo f(x)=1

The left side of the equation is what you get if you apply the "foil" method to the middle. This is the first step. Now the left-hand side is only partially factored, because you can still factor one of the remaining terms. Notice that one of the terms on the left has a similar form to that of the original question p^4-81. You can apply the same method I did to that term and then you will have fully factored p^4-81. You should have 3 factors in the end. Hope this helps!
