Answer:
20v2−40v+20
Step-by-step explanation:
=(4v+−4)(5v+−5)
=(4v)(5v)+(4v)(−5)+(−4)(5v)+(−4)(−5)
=20v^2−20v−20v+20
= 20v^2-40v+20
You can easily do this by using the FOIL method.
F - first - in this case, 4v and 5v
O - Outside - in this case, 4v and -5
I - Inside - in this case, -4 and 5v
L - Last - In this case, -4 and -5
Then you find the like terms and add them together and then you have your answer which is also in standard form.
