| Degree | Highest power of the variable: linear (1), quadratic (2), cubic (3) |
|---|---|
| By terms | Monomial (1 term), binomial (2), trinomial (3) |
| Value | p(k): put x = k |
| Zero | k is a zero if p(k) = 0. A linear ax + b has zero −b/a. |
| Quadratic ax² + bx + c | sum of zeroes = −b/a, product = c/a |
| Remainder theorem | p(x) ÷ (x − a) leaves remainder p(a) |
