Do you mean 5 a(to the second)b - 13 a b + 7 a(to the third) - 4 b 7a^3 - 5a^2b -13ab - 4b Polynomial (more than 3 terms) Degree is 9, add all exponents of variables together
Answer: Classification: polynomial (more than 3 terms)
Degree: 3
Step-by-step explanation: 5a²b - 12ab + 7a³ - 4b
As the terms are not similar, we cannot sum anything, it has 4 terms, which makes it a polynomial.
For the degree, we need to find the biggest one, which is 3 from a³.
