Solving linear and quadratic fuzzy equations. (English) Zbl 0713.04004
Linear equations of the form $$ax+b=c$$, and quadratic equations of the form $$ax^ 2+bx=c$$, $$ax^ 2+bx+d=c$$ are solved. The coefficients and the solutions are supposed to be real or complex fuzzy numbers. The solution technique is based on the extension principle. Applications in chemistry, economics, finance and physics are presented.
