Simplify the expression.

(-3f)(-4f)

Answers:

a. 12

b. -12

c. 12i

d. -12i

I don't know what you mean by f. Do you mean f=sqrt(-1) ? If so, then you have 12f^2 or -12.

If f is something else, I have no idea what the answer is.

My mistake, it's (-3i)(-4i)

well, that's obviously 12i^2 = -12

To simplify the expression (-3f)(-4f), you need to multiply the two terms together.

First, multiply the coefficients: -3 * -4 = 12

Then, multiply the variables: f * f = f^2

Combining these results, the simplified expression is 12f^2.

Therefore, the correct answer is not listed among the options provided.
