Question

Find and simplify the expression
F(3x)=(3x)^2-3

Answer 1

`\boxed{\boxed{\sf{9x^2-3}}}`

Solution Steps:

____________________________

1.) Expand
`\bold{(3x)^2}`:

• 
  `3^2x^2-3`

- 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
`\bold{3^2}`:

• 
  `3^2=9`

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

So your answer is
`\bold{9x^2-3}`.
