Types of Algebraic Expression
• Monomial expression
A monomial expression comprises of a single term. For example, 3x2, 4x, etc.
• Binomial expression
A binomial expression comprises of two unlike terms. For example, 5xy + 4, xy – 3
• Polynomial expression
An algebraic expression with more than one term with a non-negative integral exponent is called a polynomial expression.
For example, 5x2 + 3x – 1
Polynomial of various degrees
• Linear polynomial
A polynomial of degree one is called a linear polynomial, and the equation is called a linear equation.
2x – 1 is a linear polynomial in x
3z is a linear polynomial in z
• Quadratic polynomial
A polynomial of degree two is called a quadratic polynomial, and the equation is called a quadratic equation.
2x2 + 3x – 1 is a quadratic polynomial in x
3z2 – z + 2 is a quadratic polynomial in z
• Cubic polynomial
A polynomial of degree three is called a cubic polynomial, and the equation is called a cubic equation.
