Problem states: A square has sides of length 3x-2cm. Express the area of the square as a polynomial.

my answer:
(3x-2)^2 should i leave it like this or

9x^2-12x+4

I would multiply it out.

CAN YOU SHOW mE WHAT YOU MEAN. I'M CONFUSED.

Sure, I can help you with that. Multiplying out the expression means expanding the square of (3x - 2). To do this, you need to multiply each term in the parentheses by itself, then combine like terms. Here's how you can do it step by step:

1. Start by multiplying the first term in the parentheses by itself:
(3x) * (3x) = 9x^2

2. Then, multiply the first term and the second term together:
(3x) * (-2) = -6x

3. Next, multiply the second term and the first term together:
(-2) * (3x) = -6x

4. Lastly, multiply the second term in the parentheses by itself:
(-2) * (-2) = 4

Now, combine all the terms you obtained:
9x^2 - 6x - 6x + 4

Combine like terms:
9x^2 - 12x + 4

Therefore, the correct expression for the area of the square in polynomial form is 9x^2 - 12x + 4.
