Polynomial Question

What is 6x^3 - 15x^2 - 87x - 30 divided by 2x + 5? (Hint: the answer is still a polynomial)

It's 3x^2-15x-6

That is correct. Man, I'm having a challenge finding problems that take you guys more than two seconds. Honestly... Isn't math great?

(In case it's not evident- this was a joke implying that I did it with long division, which I learned in third grade.)

Hahaha! I learned long division in third grade too, and hadn't used it since. That made doing this problem rather difficult. I like synthetic division better, it's much easier.

As a side note, I should probably post only math and a few science problems, as those seem to get the most replies. Any thoughts?

I second that. They are the most interesting

Definitely. The questions on books are no good if you haven't read the book and history is kind of a specific subject that most of us don't know enough specifics to really answer. Math and science are the most fun anyway.
