Question

What is the leading coefficient of the polynomial?
15x^4 – 26x^3 – 18x^6 – 19x^7

Answer 1

-19

Explanation:

Rewrite the equation from highest exponent to lowest:

-19x^7-18x^6+15x^4-26x^3

Coefficients are the numbers in front of the exponent, so the leading coefficient is what is attached to the highest exponent value.

-19x^7 is the highest exponent, so -19 is the highest coefficient.
