Find the degree and leading coefficient of the polynomial.

-12+18x^4+15x^3+16x^2

degree 4 leading coefficient 18

Step-by-step explanation:

The degrees of the terms in the order they are written (exponent of the variable) are: 0, 4, 3, 2.

The highest degree is that of the second term, so that is the degree of the polynomial, 4.

The leading coefficient is the coefficient of that term: 18.
