Need algebra help?!?!??!

1. Dividing polynomials.

12x^2-4x-8 divided by 4x

do it like regular long division.

12x^2 / 4x = 3x remainder 0
-4x / 4x = -1 remainder 0
-8 / 4x = 0 remainder -8

so your final answer would be 3x-1 remainder -8

or if you dont want a remainder....

12x^2 / 4x = 3x
-4x / 4x = -1
-8 / 4x = -2/x

so your final answer would be 3x-1-(2/x)

you can try long division and get the same answer as this simple way since you only have one term to divide by, so

(12x² - 4x - 8) / 4x =
12x²/4x - 4x/4x - 8/4x
3x -1 - 2/x

(3*x^2 - x - 2) / x

3x -1 - 2/x
