Question

can some one help me with this problem

Answer 1

Yes! The denominators are already the same, so you can rewrite it as\[\frac{ x ^{2}-16 }{ x+4 }\]
Then you can factorise the numerator to (x+4)(x-4) (difference of 2 squares). Then, x+4 is on the top and bottom so you can cancel it out and are just left with\[\frac{ x-4 }{ 1 }\], or just x-4! Does that makes sense?

Answer 2

yes thank you
