Question

2x^5-4x^3+6x^8
is this a trinomial with a coefficient of 2 or 6?

Answer 1

6

Explanation:

Coefficient: A number before the variable such as 4 in 4x.

When there is more than one term with coefficient the leading coefficient is always the one that is in the term with the highest exponent:

2x^5 and 6x^8

^8 is bigger than ^5, so that's the leading coefficient.
