Question

Which is an expression of degree 4 which has a leading coefficient of 9 and a

quadratic term with coefficient of 10.
3
A. 9x² + 2x³ + 10x²
B. 10x + 2x³ + 9x²
C. 10x² + 9x + 4
2
D. 4 + 9x + 10x

Answer 1

None of those answers contain a polynomial of degree 4. None have a leading coefficient of 9.

Explanation:

The degree of such a polynomial is equal to the highest exponent on x.

The leading coefficient is the coefficient for the highest exponent of x.
