What are the steps to factor a polynomial?

Back

1. Look for a common factor. 2. Use special factoring formulas (difference of squares, perfect square trinomials, etc.). 3. Factor by grouping if applicable. 4. Check for irreducibility.

Front

Define the term 'leading coefficient' in a polynomial.

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial.

Front

What is the significance of the Rational Root Theorem?
