Question

Write the expression as a difference of a monomial and a trinomial: 2a^4+5a^3-2a^2+4

Answer 1

(2a^4+5a^3+4) -2a^2

Explanation:

There are 4 terms. Your trinomial could consist of any three of them. Here, we've chosen to use the one with the negative sign as the monomial, because the question asks for a difference.
