5b + 7b - b4 - 14b2 - 18b - 4b4

Question

We are learning to combine like terms. I am starting to get it and have done a few but this one frustrates me. I cannot figure it out! help?

Answer 1

11d + 13d + 8d2 - 16 + 18d2 + 11d - 9d2

This one is also confusing....

Answer 2

Combine all the b's first..you have 5b+7b-18b=-6b, you only have one b2 term, so that stays -14b2, now combine b4 terms: -b4-4b4=-5b4, so your answer is -6b-14b2-5b4. Try the next problem, and I'll check it for you.

Answer 3

15d3 + 35d - 16
15d2 + 35d - 16
17d2 + 35d - 16
17d2 + 35d - 18
It is multiple choice and these are my options.

I think its 17d2 +35 - 16

Am I right? Thanks for the help =) I appreciate it.

Answer 4

You are right. Good job.

Answer 5
