How to use vertical division?
Or what is the remainder? In fact, it's vertical division. How do you divide? The third power of x-7x + 6 divided by X-1
What's the result? How to divide?

Division is like a normal division
First of all, good. You can see that X & # 179; - 7x + 6 has the factor X-1
Then it's vertical division
First of all, quotient X & # 178;. Then just like the general division. X & # 178; * (x-1)
x³-7x+6
x³-x²
X & # 178; - 7x + 6 (remainder of the first step)
Re quoting x.x * (x-1)
x²-7x+6
x²-x
-6X + 6 (the remainder of the second step)
Re quoting - 6. - 6 * (x-1)
-6x+6
-6x+6
. 0 is exactly divisible
So factorization (x-1) (X & # 178; + X-6)
