Linear functions
Let $f:\mathbb\{R\}\to \mathbb\{R\}$ be a function defined by the relation $f(x)=ax+b,$ with a, b$\in \mathbb\{R\}$.
Quadratic equations
1. Solution formulas for $\Delta>0$
Complex numbers
The real numbers can solve first-degree equations $ax+b=0,$ $a,b\in \mathbb\{R\} cu a\neq0.$ They cannot,
