Answer: 
All you need to do here is multiply the outside number by both 7x and -3.
When done correctly it should look like this:
-14x+6
Thats the answer.
7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.
negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Answer: (pr + 1)(q + 1)</h3>
===============================================
Work Shown:
Use the factor by grouping method to get the following.
pqr + pr + q + 1
(pqr + pr) + (q + 1)
pr(q + 1) + 1(q + 1)
(pr + 1)(q + 1)
We can use the FOIL rule, distribution, or the box method to expand out (pr+1)(q+1) to get the original expression again. This helps confirm the answer.
