## 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`

.
