Answer:
Step-by-step explanation:
We have the polynomial
( 1 )
To solve this problem we have to take into account that only we can sum term with the same order in the variable. We have the polynomials
we can note (by summing term by term) that only the sum of the first and the fourth equation correspond to the given polynomial ( 1 ) of the problem. If we organize these polynomials (that is, write the equation down in a form where higher order appears first ) we have
and if we sum we obtain
that is what we was looking for
