Write the polynomial in standard form. Identify the degree and leading coefficient of the polynomia pi r^2-\frac{5}{7}r^8+2r^5l. Then classify the polynomial by the number of terms

Answer 1

It's possible that you are asking about:

although the "l" on the end could be a part of the last term, IDK if it's supposed to be there or not, but it doesn't matter for the question. To know the leading coefficient, you must put the polynomial in standard form where the term with the largest exponent (or exponent sum if there are multiple variables in the term) is in front. Here is standard form:

with largest exponents going down in order to smallest exponent.

The degree is 8 (the largest exponent) and the leading coefficient is -5/7. The polynomial has three terms so it is a trinomial.
