What is a binomial, a trinominal, and a polynomial? give examples of each.

Bionomial has 2 terms

trinomial has 3 terms

polynomial has more than 1 terms, it has a countable number of terms, the exponents of the placeholders have to be whole numbers

so bionimal could be x+2 or x³-2

trinomal could be x²+2x-3

polynomail could be all of the above, example

2x²-3x³+24x⁴-4+x
