## Quadratic Equations in One Variable

**Quadratic Equation**

Quadratic equation is in the form

$ax^2 + bx + c = 0$

Where*a*, *b*, & *c* = real-number constants*a* & *b* = numerical coefficient or simply coefficients*a* = coefficient of *x*^{2}*b* = coefficient of *x**c* = constant term or simply constant*a* cannot be equal to zero while either *b* or *c* can be zero
