This is an example of the Distributive Property. You multiply anything outside the parenthesis with everthing inside.
So...
3x*-x is -3x^2.
3x*7 is 21x.
Result...
The Product is -3x^2+21x.
Don't worry. You'll get the hang of it!

3x(-x+7)= 3x*-1x+3x*7=-3x^2+21x
It is easier to think of it as multiplying it by -1x than -x. It is just a helpful hint to some people. I know that it helps me.
