Answer:
Explanation:
standard form = combine like therms and degrees drop from left to right
In this there aren’t like therms, so:
6x^3+x^2-9x+5
therms = each therm is seprated by a plus or a minus
in this case there are 4 therms
degree = look at the monomial with the highest degree
in this case is 3
Name = in this case there are four therms so it is a quadrinomial
