Can quadratic equations be dependent equations?

Quadratic equations are called quadratic because quadratus is Latin for ''square'';in the leading term the variable is squared. also...it is form of ax^2+bx+c=0

You just have to follow the rule of quadratic functions.Example y = mx+b is the rule for linear functions.ax^2+bx+c is the rule of quadratic equation.

A complete quadratic equation is expressed in the form ax2+bx+c=0 (for example, 1x2-5x+4=0), and the formula to solve it is x1,2=(-b±√[b2-4ac])/2a {using the numbers from the example:...

The derivative of a quadratic function is always linear (e.g. the rate of change of a quadratic increases or decreases linearly).
