# Factorization of the Expression of types a 4 + a 2 b 2 + b 4 or a 4 + 4b 4

Case 1: a 4 + a 2 b 2 + b 4 type expression

In such expression types we first try to convert one part of a given expression into or form and other part into a whole square — and finally the expression is converted into the form of  and then factorization is done using factors form of as

Case 2: a 4 + 4b 4 type expression

In such type expression we convert a given expression to form by adding and subtracting last part of expression into the expression – and then get two whole square expression with subtraction sign between them.
