Some Important Mathematics Formula-
(α+в)²= α²+2αв+в²
αв ={(α+в)/2}²-{(α-в)/2}²
(α + в + c)² = α² + в² + c² + 2(αв + вc + cα)
(α + в)³ = α³ + 3α²в + 3αв² + в³
(α + в)³ = α³ + в³ + 3αв(α + в)
(α-в)³=α³-3α²в+3αв²-в³
α³ + в³ = (α + в) (α² -αв + в²)
α³ + в³ = (α+ в)³ -3αв(α+ в)
α³ -в³ = (α -в) (α² + αв + в²)
α³ -в³ = (α-в)³ + 3αв(α-в)
(α+в)²= (α-в)²+4αв
(α-в)²= α²-2αв+в²
(α-в)²= (α+в)²-4αв
α² + в²= (α+в)² - 2αв.
α² + в²= (α-в)² + 2αв.
α²-в² =(α + в)(α - в)
2(α² + в²) = (α+ в)² + (α - в)²
4αв = (α + в)² -(α-в)²
