Key Topics to Revise

1

Polynomial Multiplication

  • Product of two first-degree polynomials gives a second-degree polynomial
  • Use the distributive property: (x + a)(x + b) = x² + (a + b)x + ab
  • Mental calculation techniques for specific number patterns
2

Polynomial Factorization

  • Reverse process of multiplication - finding factors of a given polynomial
  • For x² + px + q, find two numbers whose sum is p and product is q
  • Use the identity (a - b)² = (a + b)² - 4ab to find unknown factors
3

Solving Quadratic Equations by Factorization

  • If (x - a)(x - b) = 0, then x = a or x = b (zero product property)
  • First factorize the quadratic expression, then set each factor to zero
  • This method works when the quadratic can be factored into linear terms
4

Quadratic Formula (General Solution)

  • Universal method for solving any quadratic equation ax² + bx + c = 0
  • Derived from completing the square method
  • Works even when factorization is difficult or impossible with integers
