The general form is \(a_{n}x^{n}+a_{n-1}x^{n-1}+\dots +a_{1}x+a_{0}\), where \(a_{i}\) are real numbers and \(n\) is a whole number, with examples including \(3x^{2}+5x-2\) or just \(7\) (a constant).   Key Characteristics Terms: Parts of the polynomial separated by + or - signs. Variables (Indeterminates): Letters like \(x,y,z\). Coefficients: Real numbers multiplied by variables (e.g., 3 in \(3x^{2}\)). Exponents: Must be non-negative integers (0, 1, 2, 3...). Operations: Only addition, subtraction, and multiplication are allowed; division by a variable is forbidden. Examples & Non-Examples Polynomials: \(x^{3}-2x+1\), \(5\), \(4y^{2}\). Not Polynomials: \(x^{-1}+2\) (negative exponent), \(3x^{1/2}\) (fractional exponent), \(2/x\) (division by variable). Classification by Degree Degree: The highest exponent of the variable. Linear: Degree 1 (e.g., \(x+4\)). Quadratic: Degree 2 (e.g., \(x^{2}-3x+2\)). Cubic: Degree 3 (e.g., \(x^{3}+1\)). polynomials class 9, class 9 polynomials, polynomials class 9 mcq, ch 2 polynomials class 9, polynomials class 9 cbse, polynomials class 9 ncert, maths polynomials class 9, polynomials class 9 term 2, maths class 9 polynomials, class 9 polynomials mcq, polynomials class 9 one shot, polynomials class 9 vedantu, polynomials class 9 english, polynomials concept class 9, types of polynomials class 9, class 9 maths polynomials, degree of polynomials class 9, polynomials class 9 revision, polynomials class 9 in english
