An algebraic equation which is written in the form of ax2 + bx + c = 0 where a, b and c are real numbers and a ≠ 0
Examples of quadratic equation are:
2x2 + 5x + 200 = 0
x2 - x - 20 = 0
10x2 - 4x + 36 = 0
9x2 + 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
