Recall that the GCF of two ( or more numbers) is the highest number that divides exactly the two numbers.

11.- Notice that:


\begin{gathered} 24=3\cdot8, \\ 9=3\cdot3. \end{gathered}

Therefore:


9-24=3(8-3)\text{.}

12.- Notice that.


\begin{gathered} 14x=7\cdot2x, \\ 63=7\cdot9. \end{gathered}

Therefore:


14x+63=7(2x+9)\text{.}

Answer:

11.-


3(8-3)\text{.}

12.-


7(2x+9)\text{.}
