Answer 6

is it m-5 and m+5

Answer 7

\[m^2-25=(m-5)(m+5)\]

Answer 8

what about the numerator

Answer 9

So if we make this the denominator, we can rewrite the expression as \[\frac{3(m-5)+8}{(m-5)(m+5)}\]Can you further simplify this?

Answer 10

whats the final 3m-3/m-5(m+5)

Answer 11

Not quite.\[\frac{3(m-5)+8}{(m-5)(m+5)}=\frac{3m-15+8}{(m-5)(m+5)}=\frac{3m-7}{(m-5)(m+5)}\]
