Polynomial

• An expression consisting of variables and coefficients
  • Examples
    • $x^2 - 4x + 7$
    • $x^3 - 2xyz^2 - yz + 1$
• Involves only addition, subtraction, multiplication, and non-negative integer exponentiation of variables

Degrees

• The degree of a polynomial $P(x)$ is the highest power of $x$ found in $P(x)$
  • $x^2 - 4x + 7$ has a degree of $2$
• There is no formula to give us solutions for quintic degree polynomials

	Degree	Form
Linear	1	$ax + b$
Quadratic	2	$ax^2 + bx + c$
Cubic	3	$ax^3 + bx^3 + cx + d$
Quartic	4	$ax^4 + bx^3 + cx^2 + dx + e$
Quintic	5	$ax^5 + bx^4 + cx^3 + dx^2 + ex + f$
6th degree	6	...
7th degree	7	...
