» (α+b)² = α² + 2αb + b²
» (a+b)² = (a-b)² + 4ab
» (α-b)² = α² - 2αb + b²
» (α-b)² = (α+b)² - 4αb
» α² + b² = (α+b)² - 2αb
» α² + b² = (α-b)² + 2αb
» α² - b² = (α + b) (α - b)
» 2(α² + b²) = (α+ b)² + (α - b)²
» 4αb = (α + b)² - (α-b)²
» αb = {(α+b)/2}² - {(α-b)/2}²
» (α + b + c)² = α² + b² + c² + 2(αb + bc + cα)
» (α + b)³ = α³ + 3α²b + 3αb² + b³
» (α + b)³ = α³ + b³ + 3αb(α + b)
» (α - в)³ = α³ - 3α²b + 3αb² - b³
» α³ + b³ = (α + b) (α² -αb + b²)
» α³ + b³ = (α+ b)³ - 3αb(α+ b)
» α³ - b³ = (α - b) (α² + αb + b²)
» α³ -b³ = (α - b)³ + 3αb(α - b)
