Answer 3

To expand the expression (3c - 2)^2, we'll use the formula for squaring a binomial, which is:

(a - b)^2 = a^2 - 2ab + b^2

In this case, a = 3c and b = 2. Let's substitute these values into the formula:

(3c - 2)^2 = (3c)^2 - 2 * (3c) * 2 + 2^2

Now, simplify each term:

(3c)^2 = 9c^2 2 * (3c) * 2 = 12c 2^2 = 4

So, the expanded expression is:

(3c - 2)^2 = 9c^2 - 12c + 4
