Formulas of Maths

* (a+b)2 = a2 + b2 +2ab
* a2 - b2 = (a+b) (a-b)
* (a-b)2 = a2 + b2-2ab
* (a+b)3 = a3 + b3 +3a2 b+3ab2
* (a-b)3 = a3 - b3 - 3a2 b+3ab2
* (a+b+c)3 = a3 +b3 +c3+2ab +2bc+2ac
* (x+a)(x+b) = x2 + x(a+b) + ab
* Area of a rectangle = Length*Breadth
* Perimeter of a rectangle = 2(Length + Breadth)
* Area of a Square = Side * Side
* Perimeter of a Square = 4 * Side
* Area of a parallelogram = Base * Height
* Area of a triangle = ½ * Base * Height
* Area of a trapezium = ½ * Height *(Base1 + Base2)
* Area of a circle = p * (radius)2
* Circumference of a circle = 2 * p * radius
