Key Topics to Revise

1

1. Degree and Types of Polynomials

  • The degree of a polynomial is the highest power of the variable in the polynomial.
  • A polynomial of degree 1 is called a linear polynomial.
  • A polynomial of degree 2 is called a quadratic polynomial.
2

2. Zeroes of a Polynomial

  • A real number k is a zero of p(x) if p(k) = 0.
  • For a linear polynomial ax + b, the zero is -b/a.
  • The zero of a linear polynomial is the x-coordinate where its graph cuts the x-axis.
3

3. Geometrical Meaning of Zeroes

  • The graph of a linear polynomial y = ax + b is a straight line.
  • The graph of a linear polynomial intersects the x-axis at exactly one point.
  • The x-coordinate of that point is the zero of the polynomial.
4

4. Relationship Between Zeroes and Coefficients of a Quadratic Polynomial

  • For a quadratic polynomial ax^2 + bx + c, if the zeroes are α and β, then α + β = -b/a and αβ = c/a.
  • Factorisation helps verify the relation between zeroes and coefficients.
  • For 2x^2 - 8x + 6, the factorised form is 2(x - 1)(x - 3), so the zeroes are 1 and 3.
