LCHL Functions Revision - Working with Polynomials

In this video we will look at how to work with polynomials.

In this video we will cover examples of how to:
- Find a polynomial from a Graph (using roots)
- Sketch a Graph given a polynomial
- Solve Cubic Equations using Factor Theorem
- Use Unknown Coefficient Methods to find a Polynomial.
