Types of Expressions
- An expression containing only one term is called a monomial.
- An expression containing two terms is called a binomial.
- An expression containing three terms is called a trinomial.
- An expression containing one or more terms with non-zero coefficients and variables having non-negative integers as exponents is called a polynomial.
- A polynomial can contain any number of terms, one or more than one.
Examples of Expressions
- Monomials: 4x2, 3xy, –7z, 5xy2, 10y, –9, 82mnp, etc.
- Binomials: a + b, 4l + 5m, a + 4, 5 –3xy, z2 – 4y2, etc.
- Trinomials: a + b + c, 2x + 3y – 5, x2y – xy2 + y2, etc.
- Polynomials: a + b + c + d, 3xy, 7xyz – 10, 2x + 3y + 7z, etc.
