Math (Algebra II)
posted by Sarah .
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
