http://www.freemathvideos.com In this video series I show you how to determine the leading coefficient and degree of a polynomial. We do this by first arranging the polynomial in descending order. Once the polynomial is in descending order meaning the the first term has the largest exponent. That exponent is called the degree of the polynomial. The coefficient of the variable term with the largest exponent is called the leading coefficient. x^2 + 3x^3 +27-x.
