Which expression is equivalent to the given polynomial expression?

Geography
1 answer:
EleoNora [17]2 years ago
5 0

Answer:

D

Explanation:

you have to make groupes.

start with a² part and forget the rest from example.

-4a²-a²=? Now remember - and - is adding up. so -5a², which takes out options a and b, as there are 3a² instead of 5.

now let's take ab part and forge the rest.

-2ab+6ab=? that gives us 4ab. So option c, which says 8ab, is wrong. the last number isn't really important in this case because you've already seen the rest can't be.
