You have to multiply the first term, -2x, by each of the terms within the parentheses. So it will look like this:

-2x*3 - -2x*x, and then you clean it up to: -6x +2x^2 (That's x squared). Notice that the sign in the middle changed because you are subtracting a negative term, which is the same as adding.

Nayla, multiply the -2x by each of the two terms inside the parentheses. Be sure to watch the signs (+/-).

-2x(3 - x) = -6x + 2x^2.
