Question

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

Answer 1

Answer:

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

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 $\bold{9x^2-3}$.
