**New Topic:** Polynomials, MiA Unit 2 Ch1.1

By the end of this topic you will be able to:

• use the Remainder Theorem to find remainder when dividing by x – h

• determine the roots of a polynomial equation

• use the Factor Theorem to determine the factors of a polynomial

f(x) = (2x – 1)(3x + 2)(2x – 5)
