1. The degree of a polynomial in one variable is
the greatest exponent of its variable.
The leading coefficient is the coefficient of the
term with the greatest degree.
Is the expression a polynomial in one variable? If it
is, state the degree and leading coefficient.
Yes; degree: 4 leading coefficient: 1
No; It contains two variables, a and b.
No; The term 2c–1 is not a monomial
(dividing by the variable c).
