hi guys. been trying to learn how to figure out these types of questions. having heaps of trouble. would someone be able to explain for me thankq

Step-by-step explanation:
you multiplie elements in order
first you multiple 2v by 4,than 2v by -v,than -q by 4 and finally -q by -v
it will be 8v+2v^2-4q+qv
