An algebraic equation which is written in the form of ax^{2} + bx + c = 0 where a, b and c are real numbers and a ≠ 0
Examples of quadratic equation are:
2x^{2} + 5x + 200 = 0
x^{2}  x  20 = 0
10x^{2}  4x + 36 = 0
9x^{2} + 5x  42 = 0
In order words, any equation written in the form of
p(x) = 0
where p(x) is a polynomial having degree 2
is known as quadratic equation
