In algebra, a formula is a mathematical expression that represents a relationship between two or more variables. Formulas are used to solve problems, make predictions, and generalize patterns. They are an essential tool in mathematics, science, and engineering.

a2 -- b2 = (a -- b)(a + b) (a+b)2 = a2 + 2ab + b2 a2 + b2 = (a -- b)2 + 2ab (a -- b)2 = a2 -- 2ab + b2 (a + b + c)2 = a2 + b2 + c2 + 2ab + 2ac + 2bc (a -- b -- c)2 = a2 + b2 + c2 -- 2ab -- 2ac + 2bc (a + b)3 = a3 + 3a2b + 3ab2 + b3 (a -- b)3 = a3 -- 3a2b + 3ab2 – b3

Just to make out methods...
