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 x2 b = coefficient of x c = constant term or simply constant a cannot be equal to zero while either b or c can be zero
where x1 and x2 are the roots of the quadratic equation ax2 + bx + c = 0. The sum of roots x1 + x2 and the product of roots x1·x2 are common to problems involving quadratic equation.
