Answer: trinomial
Step-by-step explanation:
Monomials have one variable (2a)
Binomials have two variables (2a - 4b)
Trinomials have three variables (2a - 4b + 7c)
Polynomials are any equations that have 4 or more variables.
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.
