#### Explanation:

First of all, you can simplify both expressions inside the square bracket: for the first one, you get

In the same fashion, for the second square bracket you get

Your multiplication is now written as

**First term times first term**:#(-3c)*(-3c)=9c^2# ;**First term times second term**:#(-3c)*7=-21c# ;**Second term times first term**:#5*(-3c)=-15c# - **Second term times second term:
#5*7=35# .

Now we sum them up:
