Question

Are the following equations either a monomial, binomial, trinomial, or none of these;

5y^5+y^3-3y
4b^2+3b^4-b^2
5x^2y-5xy^2
9a^4b^3c^2
6m^3-6m^2+6m-6

Answer 1

one trick is to count the number of addition/subtraction signs and add 1
this will give you the num of terms
monomial is 1 term
bi is 2
tri is 3
poly for more than 3
