Visualise Factor Theorem 1
The factor theorem states that:
If f(x) is a polynomial and f(a)=0, then (x−a) is a factor of f(x).

This display helps show how this comes about.

You can drag the red point to help read coordinates.

Visualise Factor Theorem 2
The factor theorem also states that:
If f(x) is a polynomial and f(ba)=0, then (ax−b) is a factor of f(x).
