3) Simplify:
[tex] {12x}^{2} - 27 \\ 4 - (2x + 1)[/tex]
​

Answer:

4+ [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Answer:

[tex]3(4x^2-9)[/tex]

Step-by-step explanation:

First, we can start by factoring [tex]12x^2-27[/tex] so that we get:

[tex]3(4x^2-9)[/tex]

Second Question:

Answer:

Step-by-step explanation:

We can get rid of the parentheses by multiplying the minus inside:

[tex]4-(2x+1)=4-2x-1 \text{ Now, we see that -1+4=3, and that we have:}\\3+2x \text{ as our final answer }[/tex]
