The problem of finding the roots of equations like the quadratic equations has many applications in applied science. In this book we introduce two new methods to solve a fully fuzzy quadratic equations (FFQE) by two new concepts. Firstly, we introduce restricted variation concept and secondly, we present the new second power of a fuzzy number and apply these concepts to solve fully fuzzy quadratic equations. All the examples were solved by maple software.
