Discuss PGroot's answer to: X^3 3x^2 6x 4 divided by x 1

I think it is missing + signs; the - signs usually come through OK.

x^3+3x^2+6x+4 divided by x+1 is x^2+2x+4.  How to do this:

first divide x^3 by x giving x^2, then multiply x^2 by (x+1) giving x^3+x^2, subtract that from x^3+3x^2+6x+4 giving 2x^2+6x+4. 

second divide 2x^2 by x giving 2x, then multiply 2x by (x+1) giving 2x^2+2x, subtract that from 2x^2+6x+4 giving 4x+4.

third divide 4x by x giving 4, multiply 4 by (x+1) giving 4x+4, subtract from 4x+4 giving 0 remainder.
