Answer 1

Step one: multiply

Step 2: divide


Hope this helps :)

Answer 2

`3(x-8)`
`3(x+5)`

Step-by-step explanation

Step 1

7)

`\begin{gathered} 3x-24 \\ \end{gathered}`

get the factors of each number

`\begin{gathered} 3x=3\cdot x \\ 24=3\cdot2\cdot2\cdot2\cdot=3\cdot8 \end{gathered}`

so, the GCF is 3

`\begin{gathered} 3x-24=3((3x)/(3)-(24)/(3)) \\ 3x-24=3(x-8) \end{gathered}`

Step 2

8)

`3x+15`

get the factors of each number

`\begin{gathered} 3x=3\cdot x \\ 15=3\cdot5 \end{gathered}`

so, the GCF is 3

`3x+15\rightarrow3((3x)/(3)+(15)/(3))\rightarrow3(x+5)`

I hope this helps you
