Answer 1

Step-by-step explanation:

An equation where the highest exponent of the variable (usually "x") is a square (2). So it will have something like x2. But not x3 etc. A Quadratic Equation is usually written ax2 + bx + c = 0. Example: 2x2 + 5x − 3 = 0.

Answer 2

In algebra, a quadratic equation is any equation that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax^2 term.
