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.
