1. A combination of constants and variables connected by +, –, × and ÷ is known as an algebraic expression.

e.g., 2 – 3x + 5x–2 y–1 + 1/3 x/y^{3}

2. An algebraic expression in which the variables involved have only non-negative integral powers is called a polynomial.

e.g., 2 – 3x + 5x^{2}y –1/3 xy^{3}

3. In the case of a polynomial in one variable, the highest power of the variable is called the degree of the polynomial.

e.g., 5x^{2} – 7x + 3/2 is a polynomial in x of degree 3.

4. In the case of polynomials in mor than one variable, the sum of the powers of the variables in each term is taken up and the highest sum so obtained is called the degree of the polynomial.

e.g., 5x^{3} – 2x^{2}y^{2} – 3x^{2}y + 9y is a polynomial of degree 4 in x and y.

5. A polynomial of degree 1 is called a linear polynomial.

6. A polynomial of degree 2 is called a quadratic polynomial.

7. A polynomial of degree 3 is called a cubic polynomial.

8. A polynomial of degree 4 is called a biquadratic polynomial.

9. A polynomial containing 1 term is called a monomial.

10. A polynomial containing 2 terms is called a bionomial.

11. A polynomial containing 3 terms is called a trinomial.

12. A polynomial containing one term consisting of a constant is called a constant polynomial.

13. The degree of a constant polynomial is zero.

14. The terms of a polynomial are said to be in ascending (or) descending order if they increase (or decrease in degrees respectively.

e.g., (i) 3 – 7x + 5x^{2} – 2x^{3} is in ascending order

(ii) – 2x^{3} + 5x^{2} – 7x + 3 is in descending order.

15. Terms with same variables and which have the same exponents are called like or similar terms, otherwise they are called unlike (or) dissimilar terms.

e.g., (i) 3x^{3}, 1/2x^{3} , – 9x^{3}, ....etc, are like terms.

(ii) x^{2}y, 3xy^{2}, – 4x^{3}, ... etc are unlike terms.

16. Dividend = (divisor × quotient) + reminder.
