Study Notes
- Factor theorem in polynomials
- Factor: a term or number that completely divides another term
- Polynomial: an algebraic expression with constant and variable terms
- Polynomial powers cannot be fractions or negative terms
- Examples of polynomials: ax² + bx + c, where a, b, c are numerical terms and x is the variable
- Example of non-polynomial: 3x^-2 + 2x^(1/2)
- Polynomial degree: highest power of the variable
- Zero polynomial: no variable term present (e.g., 5x^0 = 5)
- Linear polynomial: highest power of the variable is 1 (e.g., 2x + 3)
- Quadratic polynomial: highest power of the variable is 2 (e.g., x² + 5x + 6)
- Cubic polynomial: highest power of the variable is 3 (e.g., 2x³ + 3x² + 4x + 7)
- Remainder theorem: if a polynomial is divided by a factor, the remainder should be zero
- Example of applying remainder theorem to quadratic polynomial: x² + 5x + 6, factors are (x + 2) and (x + 3)
- Division rule: dividend = (divisor * quotient) + remainder
