• Difference of two squares
  • a²- b² = (a + b)(a - b)
    • x²- 25 = (x + 5)(x - 5), x²- 36= (x + 6)(x - 6) ,x²- 49 = (x + 7)(x - 7)
• Trinomial perfect squares
• a² + 2ab + b² = (a + b)(a + b) or (a + b)²
• x² + 14x + 49 = (x + 7)², x² + 10x + 25 = (x + 5)², x² + 12x + 36 = (x + 6)²
• ^{a2 - 2ab + b2 = (a - b)(a - b) or (a - b)2}
• x² + 14x + 49 = (x + 7)², x² + 10x + 25 = (x + 5)², x² + 12x + 36 = (x + 6)
