Math (Algebra II)
posted by Sarah on .
I'm trying to finish up my summer math packet, and I'm almost done, but I'm having trouble figuring out this one:
"Divide and simplify these expressions."
(3x^4  2x^3 + 16x  192)
/
(x^2  8)
so, that's 3x to the 4th, minus 2x cubed, plus 16x, minus 192 > all divided by x squared, minus 8
I'm checking w/ my textbook and other algebra sites to brush up on the principles, but I'm still having trouble with this one, so I'd appreciate any thoughts thanks

you are doing "long algebraic division"
make sure you left a space for the missing x^2 term or insert 0x^2 in its place
I got it to divide exactly, and my answer is
3x^2  2x + 24
It is hard to show the algorith in this forum, but here is a nice webpage to show you how to do it
