i need help on an algebra 2 question on dividing polynomials?

my algebra 2 teacher is not the best-- he just can't teach and almost all of my class fails every test because so. anyways, I'm a little perplexed on one question we've got to do for homework:

"Divide. write your answer in fraction form."

(2x^5 - 15x^3 - 9x^2 +11x + 12) / (x + 2)

the way i've been taught, we're supposed to do long division. i've gotten so far as to reaching 2x^4 -2x^3 for my answer but I just know it's got to be wrong. if anyone can help, it'd truly open my eyes a lot more.

Quick question. Are you supposed to do it by long division, or are you allowed to use synthetic division?


Aoife M.

we haven't learned synthetic division yet, I'm afraid. we're too behind.

David W. proved that what I claimed impossible is indeed possible! Thanks, David. Very nice job!
