The types of algebraic expressions are basically based on the number of terms the expression contains..
1. Monomial - contains one non-zero term
say x², 5y, 9xy²
2. Binomial - consist of two terms
say 4x + 5y, 2a + b, x² - y²
3. Trinomial - contains three terms
say x³ + 3xy + y³, 3abc + 2c - 4b
4. Polynomial - consists of one, two or more terms
- the above examples are polynomials
