$107\times 103$

If $x=1, y=2$. Find the value of $4x^2{y}^2-12xy+9$.

What is the difference between an equation and an identity? Give examples.

The exponent of a variable in a polynomial is always a whole number.

Polynomial can have one or more variables.

 Algebraic expressions with real coefficient and non-negative integers as exponents of variables are called polynomials.

A two term polynomial is called a binomial.

There can be irrational Coefficient in a polynomial.
