A quadratic equation is a polynomial equation where the highest power of the unknown is 2. If it has only one unknown, it's called a single-variable quadratic equation; if it has two, it's called a two-variable quadratic equation. The main focus is on finding the roots of the equation and analyzing their properties.

A 'quadratic graph' usually refers to the graph of a quadratic function, which is shaped like a parabola. This is an important topic in middle school math and is mainly used to describe the curved relationship between variables.

Quantum physics is a branch of physics that studies the motion laws of microscopic particles. Its core is quantum mechanics and quantum field theory, and it reveals the discontinuity and probability in the microscopic world. Along with relativity, it forms the theoretical foundation of modern physics.

A quadrilateral is a closed flat shape formed by connecting four line segments end to end, and it's one of the most basic geometric shapes in math.
