In all these videos on Polynomials from class 9th chapter 2 I have always focused on explaining the basics and then solving the questions. My way of solving question will always refer back to the basics explained previously so that students can make the connect between basics and application of them.
Let’s now start about the Polynomials:
Polynomials are the back bone of Algebra or better to say the start of algebra. We must need understand what is a polynomial to understand the algebra. In this chapter of polynomials we will will firs of all understand how to identify polynomials. What are polynomials and what is not polynomials. It is sometimes very difficult to identify them and that’s the place we make most of the mistakes. In my basic videos I have explained very clearly what is a polynomial and what is not a polynomial.

What is a Polynomial (Basics)
Variables, variables with constants, algebraic expression or just a constant
Condition: Variable, algebraic expression should have +ve integer as power
x, y, z, 2x, 5y, 4x2, (8x3 + 5z) , (2xy + 3z – xz)
2, 0, 10…..(all the real numbers are polynomials)

What is a NO Polynomial (Basics)
x-1 , 5y3/2 , 3y-7
Powers should be only non negative integer

Algebraic Identities
Identity 1: {(x+y)}^2 = x^2 + 2xy + y^2
Identity 2: {(x-y)}^2 = x^2 - 2xy + y^2
Identity 3: (x^2 - y^2) = (x + y) (x- y)
Identity 4: (x + a) (x + b) = x^2 + (a + b)x + ab
Identity 5: {(x+y+z)}^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2zx
Identity 6: \ {(x+y)}^3 = x^3 + y^3 + 3xy (x + y)
Identity 7: \ {(x-y)}^3 = x^3 - y^3 - 3xy (x - y)
Identity 8: x^3 + y^3 + z^3 - 3xyz = (x + y + z) (x^2 + y^2 + z^2 - xy – yz – zx)

We will learn about:

Zeros of a polynomial
Remainder theorem
Factorisation of a polynomial
Algebraic identities
Cubic polynomials and their factorization
Questions from all the topics and exercises.

As per the syllabus, you will learn all the topics in my Polynomial Chapter Videos:
