Simplify. (If it is already in simplest form, enter the given expression.)

x^2 − 16/
a(x + 4) − b(x + 4)

so far I have = (x+4)(x-4)/a(x+4)-b(x+4)
is there more to simplify this answer?

$$\frac{ x^2-16 }{ a(x+4)-b(x+4) } =\frac{ (x+4)(x-4) }{ a(x+4)-b(x+4) }$$

anonymous · Answer

thought the answer would be (x+4)(x-4)/a-b
 (but you cannot simplify the denominator since it has the minus/subtraction symbol correct? if you could help me understand the rule greatly appreciate it )

Can anybody see this?
