Special Situations in Factoring

  • Difference of two squares
    • a2- b= (a + b)(a - b)
      • x2- 144 = (x + 12)(a - 12)
      • x2- 144 = (x + 12)(a - 12)
      • x2- 144 = (x + 12)(a - 12)
  • Trinomial perfect squares
    • a+ 2ab + b= (a + b)(a + b) or (a + b)2
      • 3 examples
    • a- 2ab + b= (a - b)(a - b) or (a - b)2
      • 3 examples
  • Difference of two cubes
    • a3 - b3
      • 3 - cube root 'em
      • 2 - square 'em
      • 1 - multiply and change
        • 3 examples
  • Sum of two cubes
    • a3 + b3 
      • 3 - cube root 'em
