Question

Find the degree and leading coefficient of the polynomial.
-12+18x^4+15x^3+16x^2

Answer 1

• degree 4
• leading coefficient 18

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.
