For this case we must find an expression equivalent to:
[tex]\frac {\frac {m-4} {m + 4}} {m + 2}[/tex]
We apply double C and we have:
[tex]\frac {(m + 2) * (m-4)} {(m + 4) * 1} =\\\frac {(m + 2) (m-4)} {(m + 4)}[/tex]
Finally, the equivalent expression is option C.
Answer:
Option C
[tex]\frac {(m + 2) (m-4)} {(m + 4)}[/tex]
