Euclidean quotient : quo

### 2.25.2 Euclidean quotient : `quo`

`quo` returns the euclidean quotient q of the Euclidean division between two polynomials (decreasing power division) If the polynomials are represented as expressions, the variable may be specified as a third argument.
Input :

`quo(x```^```2+2*x +1,x)`

Output :

`x+2`

Input :

`quo(y```^```2+2*y +1,y,y)`

Output :

`y+2`

In list representation, the quotient of x2+2x+4 by x2+x+2 one can also input :

`quo([1,2,4],[1,1,2])`

Output :

`[1]`

that is to say the polynomial `1`.
