------------------------------------------------ What is the leading coefficient of the polynomial?

\[ 23x^5 + 12x^2 + 19x^3 + 15x^6 \]

A) 12
B) 15
C) 19
D) 23

Answer :

ANSWER

B) 15

EXPLANATION

The given polynomial is

[tex]23 {x}^{5} + 12 {x}^{2} + 19 { x }^{3} + 15 {x}^{6} [/tex]

We arrange this polynomial in ascending powers of x to obtain the standard form;

[tex] 15 {x}^{6} + 23 {x}^{5} + 19 { x }^{3} + 12 {x}^{2}[/tex]

The degree of this polynomial is 6.

The coefficient of the leading term is 15
