Ok I think I got half of this but I am not sure what to do when I multiply $\displaystyle (p-6)(p+4)$ with $\displaystyle (p+5)(p-3)$. I think I have to find the LCD. and it would be $\displaystyle (p-6)(p+4)(p+5)(p-3)$

This is the question: Simplify. State any restrictions on the variables. Remember the order of operations

The red boxes is what I dont know what to put. Please show me what to do here and how to finish the question
