Accuracy.

The general technique for graphing quadratics is the same as for graphing linear equations. However, since quadratics graph as curvy lines (called "parabolas"), rather than the straight lines generated by linear equations, there are some additional considerations.The most basic quadratic is y = x2. When you graphed straight lines, you only needed two points to graph your line, though you generally plotted three or more points just to be on the safe side. However, three points will almost certainly not be enough points for graphing a quadratic, at least not until you are very experienced. For example, suppose a student computes these three points:Then, based only on his experience with linear graphs, he tries to put a straight line through the points.

Benzene undergo substitution reaction rather than addition?

It is not always better.Although quadratic equations always have solutions in the complex system, complex solutions might not always make any sense. In such circumstances, sticking to the real number system makes more sense that trying to evaluate an impossible solution in the complex field.

If the process of substituting leads to an identity rather than an equation then the system has infinitely many solutions.

There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.

You will obtain a more accurate answer than is possible using graphical methods. It's faster and less work than using a table.

The overwhelming majority of chemical equations do involve molecules, but if they don't, you can call them chemical equations rather than molecular equations.
