Polynomial Division Help - x^3 + 4x^2 - 3x - 12 & -x^3 + 75x - 250

AI Thread Summary
Polynomial division involves dividing one polynomial by another to simplify the expression. The user seeks assistance with two specific problems: dividing x^3 + 4x^2 - 3x - 12 by x^2 - 3, and -x^3 + 75x - 250 by x + 10. They express difficulty in understanding the division process despite trying tutorials. Guidance is offered to review instructional materials on polynomial division for clarity. The discussion emphasizes the importance of understanding the division method to solve the problems effectively.

I can't seem to get it... I need some help with 2 of the problems below:

x^3 + 4x^2 - 3x - 12
over
x^2 - 3

and

-x^3 + 75x - 250
over
x + 10

I've tried tutorials and everything, I can get a few but these are just a little tricky for me.

Any help is appreciated. :)

What exactly are you suppose to do?

Simplify into a polynomial?
 
Thanks for the reply! I'm suppose to divide them. Thanks. :)
 
I think you should look again at your book to see how one can divide a polynomial by another polynomial.
Or you can look here. It shows you how to divide polynomials, and also provides some examples. From there, you can do the 2 problems, right? :smile:
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
