Divide 2-7x^2+x^4-2x-x^3 by x+2
Put your polynomials in descending order.
divided by x+2
You didn't specify that I had to use long division which is very difficult to me to illustrate because I don't know all the java commands to allow for spaces and lines. I'm using synthetic division.
Change the sign of 2 in x+2, that's on the outside. Put the coefficients on the inside:
-2|1 -1 -7 -2 2
::|
--------------- Bring down the 1
:: 1
:
-2|1 -1 -7 -2 2
::|0 -2
---------------- Multiply -2 by 1 and put it under -1
:: 1
:
-2|1 -1 -7 -2 2
::|0 -2
----------------- add -1 and -2 and put the answer under them
:: 1 -3
:
-2|1 -1 -7 -2 2
::|0 -2 6 2 0
------------------ Repeat the steps until you have this.
:: 1 -3 -1 0 2
These are the coefficients of your polynomial starting 1 degree less than what you started with. The last number is the remainder.
r=2
r=2 Sometimes you write the remainder as the numerator and the divisor as the denominator.

Happy Calculating!!!
