if you have to show ur work here it is…
x-1(division bar —) x^3+2x^2+3x-6 this allows easy set up
and then just divide one at a time
what goes into x^3 mult. by x which would be x^2, so you put x^2 on top of the division bar, and then x^2 times x-1 equals x^3-x^2, and you subt. from your problem which leaves 3x^2+3x-6….then what times x equals 3x^2 which would be +3x which goes beside x^2, so then you mult and that equals 3x^2-3x and you subtract and are left with 6x-6, then you do the same thing get +6 to put on top of bar, multiply and get 6x-6, subtract and get 0 and you’ve solved the problem
x^3 + 2x^2+3x-6
you can check by multiplying your answer by x-1 to see if you get the original problem
then the next problem
do the same thing and you get n^2+3n+9
