A quadratic typically has the form of ax^2 + bx + c = 0 however the only requirement is that |a|>0, there is not factor of x to a power higher than 2 and no other function involved ie x^3 is not a quadratic. Notice also that x^2 + sin(x) +3 is not quadratic. In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1.
