1. Multiplying Rational Equations

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

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

the numerators of the "problem" functions are the same in line 2 as they are in line 3. thus the denominators must be the same. what you should have done in moving from line 2 to line 3, is cancel the (p - 6)'s, the (p + 4)'s and the (p - 3)'s from the numerator and denominator
