Question

What is a quadratic equation ?​

Answer 1

Answer:

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.

Answer 2

Answer:

In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as

{\displaystyle ax^{2}+bx+c=0} ax^{2}+bx+c=0

where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0.
