Answer:
[tex]3(x+6)[/tex]
Step-by-step explanation:
For this question, you have to multiply what is outside the parenthesis with what's inside the parenthesis. Like this:
- [tex]3(x-6) = \\3 \times x \; \text{and} 3 \times - 6 \rightarrow 3x-18x[/tex]
- [tex]3(x+6) = \\3 \times x \; \text{and} 3 \times +6 \rightarrow \boxed{3x+18}\\[/tex]
- [tex]3(x+18) \\3 \times x \; \text{and} 3 \times +18 \rightarrow 3x + 54[/tex]
Therefore, the second option is the correct one, because factoring [tex]3(x+6) = 3x+18[/tex].
