Topics in Polynomials
Introduction to Polynomials
- A polynomial in one variable x is an expression of the form: aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀
- Coefficients (a₀, a₁, ..., aₙ) are constants, and aₙ ≠ 0 for degree n
- Each part like aₙxⁿ is called a term of the polynomial
Types of Polynomials
- Classification by number of terms: Monomial (1 term), Binomial (2 terms), Trinomial (3 terms)
- Classification by degree: Linear (degree 1), Quadratic (degree 2), Cubic (degree 3)
- Standard forms: Linear: ax + b, Quadratic: ax² + bx + c, Cubic: ax³ + bx² + cx + d
Zeros of a Polynomial
- Zero of p(x): A value 'a' such that p(a) = 0
- Finding zeros: Solve the equation p(x) = 0
- Linear polynomial: exactly one zero at x = -b/a
Remainder Theorem
- If polynomial p(x) is divided by (x - a), remainder = p(a)
- Division: p(x) = (x - a) × q(x) + p(a)
- No actual division needed - just substitute x = a
