Given:
The polynomials are:


To find:
The completely simplified sum of the polynomials.
Solution:
We have,


The sum of given polynomials is:


Therefore, the sum of the given polynomials is
. It is a polynomial with degree 6 and leading coefficient -2.
4x^2+4x-8=0
X^2+x-2=0
(X+2)(x-1)=0
X= -2 or 1
