Question

What is the leading coefficient of the polynomial?

23x5 + 12x2 + 19x3 + 15x6
A) 12
B) 15
C) 19
D) 23

Answer 1

B) 15

Step-by-step explanation

The given polynomial is

`23 {x}^(5) + 12 {x}^(2) + 19 { x }^(3) + 15 {x}^(6)`

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

`15 {x}^(6) + 23 {x}^(5) + 19 { x }^(3) + 12 {x}^(2)`

The degree of this polynomial is 6.

The coefficient of the leading term is 15
