# How do you write the polynomial so that the exponents decrease from left to right, identify the degree, and leading coefficient of the polynomial 5z+2z^3-z^2+3z^4?

$3 {z}^{4} + 2 {z}^{3} - {z}^{2} + 5 z$
Recall that the degree of a polynomial is the degree of its higheset term. In this case, it is a 4th degree polynomial because the $3 {z}^{4}$ is the highest exponent.
