Some More identities!!

• (a + b)² = a² + b² +2ab

• ( a - b )² = a² + b² -2ab

• ( a² - b² ) = ( a - b ) ( a + b )

• ( a +b +c)² = (a² + b² + c²) + 2(ab + bc +ca)

• (a + b)³ = a³ + b³ + 3ab(a+b)

• (a-b)³ = a³ - b³ -3ab(a-b)

• ( a³ + b³) = (a+b) (a²-ab +b²)

• (a³ - b³) = (a -b) (a² + ab + b²)

• Area of Square = Side × Side

• Area of Rectangle = Length × Breadth

• Area of Rhombus = 1/2 × d1 × d2

here

d1 is the 1st diagonal of Rhombus

d2 is the second diagonal of Rhombus

• Area of Parallelogram = Base × Height

• Perimeter of Square = 4 × Side

• Perimeter of Rectangle = 2 (Length + Breadth)

• Area of Triangle = 1/2 × base × height

• Perimeter of triangle = Sum if their sides

• Circumference of Circle = 2πr

where,

π = 22/7

r is the radius of Circle
