A parabola is a shape. There’s nuance and ‘why’s as well, but at its core that’s all that ‘parabola’ means, just like a line or a circle or a square is a shape.
Quadratic comes from the latin word for ‘square’, and it means an equation where there’s a ^2 (aka a square) involved. Lots of interesting things can be done with them, but because there’s so many things it’s hard to know where to start for ELI5 beyond this.
One of the neat things about a quadratic equation on a graph, it forms a parabola. But once again, there’s nuance involved, as well as a *ton* of supporting topics that can help make it easier to understand if you already know them. What sort of questions do you have about the two and how they relate?
