( v – 4 ) ( v + 8 )

Question

multiply

( v – 4 ) ( v + 8 )

Answer 1

First, multiply (v-4) times v and you get v² - 4v.

Then multiply (v-4) times 8 and you get 8v - 32.

Now add the two results together and you get v² - 4v + 8v - 32.

Then, you can combine the -4v and + 8v to get + 4v. The final result is:

v² + 4v - 32.
