Topics in Polynomials
Types of Polynomials Based on Degree
- Degree of a polynomial is the highest power of the variable in the polynomial
- Linear polynomial: Degree 1 (Example: 2x - 3, √3x + 5)
- Quadratic polynomial: Degree 2 (Example: 2x² - 3x + 5, y² - 2)
Value of a Polynomial and Zeros
- Value of polynomial p(x) at x = k is denoted as p(k)
- To find p(k), substitute x = k in the polynomial expression
- A real number k is called a zero of polynomial p(x) if p(k) = 0
Geometric Representation and Graphs
- Graph of linear polynomial y = ax + b is a straight line
- Linear polynomial has exactly one zero (x-intercept)
- Graph of quadratic polynomial y = ax² + bx + c is a parabola
Relationship Between Zeros and Coefficients
- For quadratic polynomial ax² + bx + c with zeros α and β:
- Sum of zeros: α + β = -b/a
- Product of zeros: αβ = c/a
