Formula of Mathematics

Some important formula of Mathematics

• (α+в+c)²= α²+в²+c²+2(αв+вc+cα)
• (α+в)²= α²+2αв+в²
• (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
• (α+в)² - (α-в)² = 4αв
• 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)
