    Study Notes

    Polynomials: An Introduction

    Polynomials are mathematical expressions that consist of variables and coefficients combined using the operations of addition, subtraction, and multiplication. They are expressed in the form of a_n x^n + a_{n-1} x^{n-1} + ... + a_1 x + a_0, where a_n to a_0 are coefficients, x is a variable, and n is the highest power of x.

    Degree of a Polynomial

    The degree of a polynomial is the highest power of the variable in the expression. For example, in the polynomial 3x^2 + 2x + 1, the degree is 2, since the highest power of x is 2.

    The degree of a polynomial can be determined by looking at the highest power of the variable in the expression. If the polynomial has the form ax^n, where a is a constant and n is the highest power of x, then the degree is n.

    Zero Polynomial

    A polynomial is considered zero if all of its coefficients are equal to 0. For example, 0x^3 + 0x^2 + 0x + 0 is a zero polynomial. The degree of a zero polynomial is 0.

    Constant Polynomial

    A constant or linear polynomial is a polynomial with degree 1. For example, 5x + 4 is a constant polynomial.

    Quadratic Polynomial

    A quadratic polynomial is a polynomial with degree 2. For example, 3x^2 + 2x + 1 is a quadratic polynomial.

    Cubic Polynomial

    A cubic polynomial is a polynomial with degree 3. For example, x^3 + 2x^2 + x + 1 is a cubic polynomial.

    Degree of a Product

    The degree of a product of polynomials is the sum of the degrees of the factors. For example, if p(x) = x^2 + 2x + 1 and q(x) = 2x^2 + 3x + 4, then the degree of their product p(x)q(x) is 2 + 2 = 4.
