Topics in Polynomials
Introduction to Polynomials
- A polynomial in x is an expression of the form anxn + an-1xn-1 + ... + a1x + a0, where coefficients are real numbers
- The highest power of the variable determines the degree of the polynomial
- Expressions like 1/x + 1, √x + 2 are NOT polynomials because they contain negative or fractional powers
Geometrical Meaning of Zeros
- Zeros of a polynomial are x-coordinates where its graph intersects the x-axis
- Linear polynomial: graph is a straight line, exactly one zero
- Quadratic polynomial: graph is a parabola, can have 0, 1, or 2 zeros
Relationship Between Zeros and Coefficients
- For quadratic ax² + bx + c with zeros α, β: Sum = -b/a, Product = c/a
- These relationships help find unknown coefficients or zeros
- Can construct polynomials when zeros are given
Problem-Solving Techniques
- Method 1: Factorization by splitting middle term
- Method 2: Using zero-coefficient relationships
- Method 3: Completing the square
