täydennysmenetelmä
Täydennysmenetelmä, often translated as "completion method" or "filling-in method," is a mathematical technique used in algebra, particularly in the context of quadratic expressions. Its primary purpose is to rewrite a quadratic expression in a standard form that reveals its vertex or allows for easier manipulation, such as solving equations.
The most common application of the täydennysmenetelmä is transforming an expression of the form ax² + bx
This method is fundamental for deriving the quadratic formula, graphing parabolas, and solving quadratic equations without
