Canonical form

### 9.1.7 Canonical form

The canonical form of a second degree polyomial in a variable x is the form a(x−c)2+b.

The canonical_form command finds the canonical form of a second degree polynomial.

- canonical_form takes p, a second degree polynomial.
- canonical_form(p) returns the canonical form of p.
