Okay, here we have this:
Considering the provided polynomial, we are going to clasify it, so we obtain the following:
Since it has three terms with the variable raised to different exponents, then it means that it is a trinomial.
Leading Coefficient: Let us remember that the leading coefficient is the one that accompanies the variable with the highest exponent, so in this case the variable with the highest exponent is w^2, therefore the leading coefficient is 5/9.
Degree: The degree of a polynomial is the highest exponent to which the polynomial variable is raised, in this case the highest exponent is 2, so the polynomial has degree 2.
