Question

what are the leading coefficient and degree of the polynomial ?

-23-20u^2 + u^6 +15u

Answer 1

First you need to put the polynomial in order from the biggest exponent to the smallest

u⁶-20u²+15u-23

The leading coefficient is the number in front of the variable with the largest exponent.

In this case that would be the imaginary 1 in front of the u⁶

The leading coefficient is 1

The degree of this polynomial is the highest exponent which is 6
