Question

What is the leading coefficient of the polynomial?

3x2 + 5x3 − 4x4 − 7x

Answer 1

-4

Explanation:

Rearranging the terms of this polynomial in descending order by powers of x, we get 3x2 + 5x3 − 4x4 − 7x => -4x^4 + 5x^3 + 3x^2 - 7x.

-4x^4 is the leading power of x, and -4 is the "leading coefficient" of the polynomial.
