Chapter 2 : Polynomial What is polynomial? A polynomial is an expression made up of variables and coefficients, combined using addition, subtraction, and multiplication, with non-negative integer exponents. Example : 3x 4 -2x 2 +7x-5. Key Features of Polynomial : let's discuss some features of polynomial: Take a polynomial : 3x 4 -2x 2 +7x-5. a) Degree: The highest power of the variable(x)(e.g. degree of 3x 4 -2x 2 +7x-5 is 4). b) Terms: Each part separated by + or – (e.g., 3x 4 , -2x 2 , 7x, -5). c) Coefficients: Numbers multiplying the variables (e.g., 3, -2, 7). d) Constant term: The standalone number (e.g. -5). Types of polynomial: a) Linear polynomial: A polynomial of degree 1.     Example : 2x – 3 , u + 5 , 3u+ 5 b) Quadratic polynomial : A polynomial of degree 2     Example : 3x 2 +2x – 3 ,3u 2 - u + 5 c) Cubic polynomial : A polynomial of degree 3     Example : 2...
