Answer:

[tex]\boxed{\boxed{\sf{9x^2-3}}}[/tex]

Solution Steps:

____________________________

1.) Expand [tex]\bold{(3x)^2}[/tex]:

  • [tex]3^2x^2-3[/tex]

 - We do this to make the problem easier to simplify. When expanded you can easily figure out what you need to find to make it a simplified equation.

2.) Calculate [tex]\bold{3^2}[/tex]:

  • [tex]3^2=9[/tex]

 - We do this because it's the only thing we can find, that would make this a simplified problem.

So your answer is [tex]\bold{9x^2-3}[/tex].
