### 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 *x*^{2}+2*x*+4 by *x*^{2}+*x*+2
one can also input :

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

Output :

`[1]`

that is to say the polynomial `1`.
