__A Review Of Some Concepts (for myself):__**Remainder Theorem**:

When dividing a polynomial expression p(x) by a linear polynomial expression x-b, the remainder is p(b).

**Factor Theorem:**

A linear expression x-b is only a factor of p(x) if p(b) is 0. (So there must not be any remainder)

**Integral Zero Theorem:**

If x=b is an integral zero of the polynomial P(x), then the constant term of P(x) must be divisible by 2.

**Rational Zero Theorem:**

If x=b/a is a rational zero of the polynomial P(x), then the constant term of P(x) must be divisible by b, and the leading coefficient must be divisible by

*a*.
