The difference between these terms is that a monomial has one term, bi has two, tri has three. Once you understand how these equations are built then they become relatively easy to see and distinguish from one another. Now math is not my strong suite so 4 could also be a trinomial but I'm pretty sure it's none of the above. Good luck!
There are many different kinds of quadrilaterals, but all have several things in common: all of them have four sides, are coplanar, have two diagonals, and the sum of their four interior angles equals 360 degrees. This is how they are alike, but what makes them different?
