Question

Part 2: Add the following polynomial. Once simplified, name the type of polynomial. 4.) (7x^3 - 6x^2 + 4x + 1) + (2x^3 + 5x^2 - 4x -9) Type:

Answer 1

Add the polynomial terms.

$7x^3-6x^2+4x+1+2x^3+5x^2-4x-9=9x^3-x^2-8$

There are three terms in polynomial expression. So the expression is called trinomial.
