Polynomial Functions

Quintic
f(x) = ax^5
Quartic
f(x) = ax^4
Cubic
f(x) = ax^3
Quadratic
f(x) = ax^2
Linear
f(x) = ax

Polynomial Functions in general form:

f(x) = a(nx)^n + a(n-1)x^(n-1) + a(n-2)x^(n-2) + ... a(3)x^3 + a(2)x^2 + a(1)x + a
Notes: -

Factoring

Sum of Cubes
f(x) = a^3 + b^3 = (a + b)(a^2 - ab + b^2)
Difference of Cubes
f(x) = a^3 - b^3 = (a-b)(a^2 + ab + b^2)
Difference of Squares
f(x) = a^2 - b^2 = (a+b)(a-b)
Factoring less simple trinomials
f(x) = ax^2 + bx +c (where a =/ 1) (DON'T FORGET TO GROUP FACTOR)
Factoring Simple Trinomials
f(x) = x^2 + bx + c (where a = 1)
Common Factoring
f(x) = ax^2 + bx (factor out commonality in each term)
