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 questionnaire survey refers to a method where you create a detailed and thorough questionnaire and ask respondents to answer it to collect information.
