The term “quadratic” comes from the word “square.” A polynomial equation has only non-negative integer powers of x. The most significant power is 2. Hence it is a second-degree polynomial. Thus, an equation’s degree is 2. Quadratic functions are used in engineering and research to calculate parameters. A parabola represents them graphically. The most significant degree coefficient determines the curve’s orientation. Many situations call for quadratic functions. Unfortunately, a quadratic function is not always expressed in standard form. Differentiation can find the maxima and minima of quadratic functions.
