In algebra, a quadratic equation is any polynomial equation of the second degree with the following form: ax 2 + bx + c = 0. where x is an unknown, a is referred to as the quadratic coefficient, b the linear coefficient, and c the constant. The
The quadratic function with a > 0 has a minimum point at (-b/2a , f (-b/2a)) and the function is decreasing on the interval (-infinity , -b / 2a) and increasing over the interval (-b / 2a , + infinity). case 2: coefficient a < 0 We divide both sides of the
